We are doing a migration of sales orders from an old system to Dynamics CRM online. In the old system we have one amount in one currency and other amount in base currency(USD). The ratio between those two is the exchange rate that was valid in time the original record was created.
Is there a way how can we transfer old orders so that the exchange rate stays the same? Currently it gets overwritten by the current exchange rate for given currency.
For any currency attribute in CRM you can unfortunately not set the _base currency or exchangerate directly. Otherwise that would be the easiest solution. As a work-around you can instead use the following solution:
As mentioned here, CRM supports registering plugins on the RetrieveExchangeRate message. Normally the exchange rate is taken from the transaction currency, but you can override that. You could register a plugin on this message which returns the needed exchange rate for the specific record. How you find the correct exchange rate would depend on your exact situation, but one way could be to first store all the historical exchange rates in a custom entity. You would then subsequently run your import of data.
In your plugin running on RetrieveExchangeRate you would look up the relevant exchange rate from the custom entity and return it, resulting in the imported data having the correct exchange rates.

We're building a marketplace in NEAR. We have two smart contracts for token and marketplace. Same as NEAR example.
In our platform, we have successfully implemented below features:
Token mint (used contract method: nft_mint)
Token listing for sale at Fixed Price in marketplace (used contract methods: storage_deposit nft_approve)
Token purchase (used contract method: offer)
Apply creator royalty at mint time.
Apply service fee (Transaction fee of Marketplace) on each sale.
Everything is working fine.
Now, we would like to implement the Timed Auction Functionality
Creator can create NFT’s to be sold as an auction so that buyers can bid on them to get a higher price.
Method:- Sell to the highest bidder: where the highest bid wins at the end.
Making a bid on this kind of auction is like making an offer on a fixed-price listing. The seller can choose to accept it at any time, but the buyer will near of the amount of bid to create a bid.
Questions:
How we can implement the Timed Auction Functionality with Marketplace
Contract?
Do we have any documentation or example for the
Timed Auction Functionality?
Example of OpenSea's Timed Auction Functionality:
You can't do that directly from within a contract since the contract does not run all the time you will have to call function trough something like https://cron.cat/ or your own.
Contracts perceive time trough current execution so when a function is called env::block_timestamp_ms() within said fn would give us the current time of execution, you can subtract time from it to get some time in the past. We can do manual checks like is the time stamp past this than do that or the less accurate is the blockheight above certain threshold but all this will have to be executed within a function that needs to be called.
I will preface this post by saying that this is how I would go about solving this in a simple way. There are more complex solutions out there but I'll try and keep it relatively simple. (scroll to the bottom for a TLDR).
Here's a solution to the timed auction functionality. In the marketplace example that you posted, what you'll want to do is store two extra fields in the sale object indicating the desired length of the auction as well as the time when the sale was listed.
Whenever NFTs are put for sale (in the nft_on_approve function), you'll need to add the current block_timestamp (which will give you the number of nanoseconds since the Unix epoch). You'll also need to store the desired length of the auction which is up to you as to how you would like to implement that. It can be time in nanoseconds, milliseconds, seconds, days, either since the Unix epoch or the actual desired duration of the auction.
Once your sale object contains both these new fields, all you would need to do is whenever an offer is made, check if the current block timestamp is within the desired auction length. If it is, proceed, if it's not panic. Since the marketplace can't constantly be polling to see if the auction is finished, a common approach is to use the functionality I described above:
You either bid on the NFT before the timestamp or you didn't. If you did, your bid is accepted, if you don't, it panics.
At this point, there is no way for the marketplace to automatically transfer the NFT to the highest bidder the second the auction closes (due to the marketplace's inability to poll). My suggestion here would be to have a claim function that the highest bidder must call if they want the NFT transferred to them. You can get spicy with this and have timeouts whereby if it isn't claimed within 5 days, the original owner can claim it back but for the sake of simplicity, let's not get into that.
As for the bidding mechanic, there's many different ways you can do this. I'll go over one of the more simple approaches. Currently, when a sale is listed with sale conditions, the NFT can only be purchased for more than or equal to the price as shown here. What you'll want to do is store active bids in the sale object.
You'll need to store both the current highest bidder as well as their bid amount. This will be initialized to empty when the NFT is listed and then once an offer is made for less than the desired list price, it's considered a bid. Bids will only be added if they are less than the desired price and greater than the highest current bid. If the offer is more than the list price, the NFT is automatically sold and the purchase is processed.
Combining everything I've outlined so far in a TLDR:
What you would need to add as a minimum PoC to the sales object:
Store desired length of auction (in whatever format you want)
Store date of listing
Store current highest bidder
Store current highest bid
Listing mechanics:
When a sale is listed, set the date of listing and the desired length of the auction.
Offer mechanics:
make sure the attached deposit is greater than the current highest bid (if none, make sure it's >= 0).
If the attached deposit is greater than the list price, process the purchase. If it's not, add it as the current highest bid.
Make sure that the any offers are made within the desired length of the auction. If they aren't panic, if they are, you're good to go.
If somebody is outbid, make sure you refund them for their deposit!
Claim mechanics:
Claims can only be made if the auction time has passed. Only the highest bidder can claim the NFT. Once claimed, the purchase is processed.
I am working on a SAAS project where users can create various projects. With each project, they can choose from 5 different plans. Each plan has its own costs per month. Hotjar is a kind of equal concept.
Now I want to arrange the subscription with Stripe. The problem with that was that a user can have a maximum x subscription, which of course was a shame. Then I decided to take 1 subscription that has several plans. But now I have a dilemma, to update the subscription you have to change the number via SubscriptionItem. Then you have to save yourself which plan has which SubscriptionItem_id for which user. That is quite a detour and can cause many problems.
Someone is a better way with Stripe or another payment software.
You don't necessarily need to store the subscritpion_item IDs, you can look it up via the subscription_item list API. All you need to do is store the subscription_id for your customers, and based on that ID you can retrieve the list of subscription_items:
\Stripe\Stripe::setApiKey("sk_test_9GavlLpfiKewqeCBXvRvmVgd");
\Stripe\SubscriptionItem::all(["subscription" => "sub_EQlPGjVj4o5luH"]);
Then you can handle the data part of the returned JSON object and update / delete / etc these subscription items.
If you only have the customer_id handy, then you can use the subscription list API (with status as well on the GET params) to retrieve the list of active subscriptions.
I am new to CRM. I was reading here that there is a "convert lead to account, contact and opportunity". I understand how it would split the data from lead to account and contact, but I can't see ( from reading the Entity Metadata excel file ) where any opportunity information would be linked to lead.
If I understand your question correctly, you are looking for Originating Lead lookup in Opportunity entity record where the Qualified Lead entity record reference will be stored.
If you want to store more Lead record values into Opportunity record, you can use entity relationship mapping like explained in this blog.
Update:
If you don’t want to create a Contact when qualifying, you will need to associate the Lead to an existing Contact in Dynamics CRM 2015. An Opportunity will always be created regardless of which fields are populated on the Lead.
In fact, if you didn’t fill out a single field on the Lead form (none were set to ‘required’), and Qualified that Lead, you would create a new Opportunity with no information associated to a new Contact that also has no information.
Of course, you can use workflows to adjust these situations as required – e.g. if you never want an Opportunity to be created from a Qualified Lead you could write a workflow to delete the Opportunity on creation (checking to make sure the Originating Lead has a value).

I'm trying to create a recurring payment on Square, ala Stripe subscriptions. However, I am having trouble retrieving a customer's card information (specifically customer_card_id) to pass into Charge.
Our flow is such:
A customer visits to our store and subscribes to a membership, which we process via the point of sale app.
We continuously poll Square to retrieve payment information, and create membership records appropriately.
When the user's membership period expires, charge them for the next month's membership.
When researching RetrieveCustomer, I find that there is a cards property under Customer, but iterating through all the Customers under our account, they all have cards = None despite us having taken card payments via the point of sale app.
Also, looking at ListTransactions, there doesn't seem to be anything that might be customer_card_id. The IDs I see there are tender ID, location ID, and transaction ID. The card_fingerprint also looks promising but that doesn't seem right either, since a card can have both an ID and a fingerprint.
Am I missing something? Where might I find customer_card_id?
EDIT
Looks like I was dumb and my local instance of our application was just out of date with transactions from Square. After updating my data with customers we've processed since the last time I updated, customers with a non-None card property now show up. tristansokol's answer below is still valid however.
How do you process the first charge? You need to explicitly add the card on file, it won't be added by default from processing a transaction from a customer. See: https://squareup.com/help/us/en/article/5770-use-card-on-file-with-the-square-point-of-sale-app
I have a web application that syncs Outlook contacts to a database (and back) via CDO. The DB contains every contact only once (at least theoretically, of course doublets happen), providing a single point of change for a contact, regardless of how many users have that particular contact in Outlook (like Interaction or similar products).
The sync process is not automatic, but user-initialized. An arbitrary timespan can pass before users decide to sync their contacts. A subset of these contacts may have been updated by other users in the meantime.
Generally, this runs fine, but I have never been able to solve this fundamental problem:
How do I doubtlessly identify a contact object in a mailbox?
I can't rely on PR_ENTRYID, this
property changes on contact move or
mailbox move.
I can't rely on my own IDs (e.g. DB
table ID), because these get copied
with the contact.
I absolutely can't rely on fields
like name or e-mail address, they
are subject to changes and updates.
Currently I use a combination of 1 (preferred) and 2 (fall-back). But inevitably, sometimes users run into the problem of synching to the wrong contact because there is none with a given PR_ENTRYID, but two with the same DB ID, of which the wrong one is chosen.
There are a bunch of Outlook-synching products out there, so I guess the problem must be solvable.
I had a similar problem to overcome with an internal outlook plugin that does contact syncing. I ended up sticking a database id in the Outlook object and referring to that when doing syncs.
The difference here is that our system has a bunch of duplicates that get resolved later by the users. When they get merged I'll remove the old records and update outlook with all of the new information along with a new id.
You could do fuzzy matching to identify duplicates, but duplicate resolution is a funny problem that's mostly trial and error. We've been successful at implementing "fuzzy" matching logic using the levenshtein distance algorithm for names and addresses cleaned down to a hash code.
Good luck, my syncing experiences have been somewhat painful.
