I am trying to share my location to a card with following steps:
create a ticket with API /users/self/create_ticket
set the card_id of the ticket with API /tickets/:id/append_data
share ticket to a card with API /cards/:id/ticket, invite_code: random string like pUsl_79rB
append location into the ticket whit API /tickets/:id/append_location
Then I retrieve card members with API /cards/:id?members=true, I can see the ticket just created and shared to the card.
But the problem is that the invite_code is always "00" like following:
"ticket": {"invite_code": "00", "ticket_id": "160064993", "created_time": 1506573004818}
With invite_code "00", no one can get the location I shared.
Please help.
thanks.
You need to create invite code for the ticket created in step 1). So your step 1.1) would involve calling `POST tickets/:id/create_invite?type=link'. This will provide you with the code that goes to the card in step 3).

I'm getting an error with Plaid that my rate limit has been exceeded, since I have 5 items in use on my developer account. I have only used Plaid on my localhost from my browser, and the quickstart app to look up my actual accounts. I'm confused how it thinks these are new systems - and also how to release one of these items so it frees up developer slots. The documentation says I can hit the release route, but that that doesn't restore an item slot.
Is there anything I'm missing?

"documentation_url": "https://plaid.com/docs/?ref=error#rate-limit-exceeded-errors",

Ah yes you are not the first person to be confused by this! You need to request access to Development via the Plaid dashboard, which, once approved, will unlock access to 95 additional Items. You can do this here: https://dashboard.plaid.com/overview/development
The number of computers you are using doesn't matter, the only thing being counted is Items -- each Item takes up one slot, but in Development deleting Items does not free up slots.
Is it legal and possible to:
1. Get PKPaymentToken in iOS app
2. Send this token to server side
3. Decrypt this PKPaymentToken (ex. based on many available GitHub libraries)
4. I have now:
{
"applicationExpirationDate": "190131",
"applicationPrimaryAccountNumber": "370295XXXXX5435",
"currencyCode": "840",
"deviceManufacturerIdentifier": "XXXXXXXXXX",
"paymentData": {
"emvData": "nycBgJ82AgDCnyYIG2vuQydGkMafEAcGhgEDoLABXzQBAJUFgAABAACCAhzAnwMGAAAAAAAAnxoCCECaAxQQBJwBAJ83BLnvab4="
},
"paymentDataType": "EMV",
"transactionAmount": 100
}
5. Use this data to make transaction in such way:
Here I have doubt!
To make transaction I can use only this EMV or 3DS cryptogram in paymentData -> emvData (or 3dsecure)
Or I can use applicationPrimaryAccountNumber as casual Card Number (or maybe this is different from Card Number printed on physical plastic Card?)
Why I am asking? On the server, I have integration with another external system that handles transactions. And there is a library that takes credit card information (card number, expiry date, cardholder) to make the transaction.
Will I be able to use this decrypted data to pass raw card number, exp date, cardholder to this library to make transaction payment happen.
Or this library must be able to handle this EMV, 3DSecure cryptograms only?
Thanks for the clarification.
Is there an API to get a user's steam trading cards?
I'm not very familiar with steam but it doesn't seem to be on this page.
https://developer.valvesoftware.com/wiki/Steam_Web_API#GetPlayerSummaries_.28v0001.29
There's an achievements API would that get me the trading cards info as well?
There is not an API for the trading cards (yet). You can, however, still find them. It does depend on the user's privacy settings though. I went into more detail on this question and believe it will help you out.
Achievements can be pulled via the GetPlayerAchievements API call using the following format:
http://api.steampowered.com/ISteamUserStats/GetPlayerAchievements/v0001/?appid=<APPID>&key=<APIKEY>&steamid=<PROFILEID>l=<LANG>
APPID is the application ID the achievements are associated with (ie. Team Fortress 2 is 440)
APIKEY is the API key Valve assigned you
PROFILEID is the 64bit player ID give to you when you sign up on steam
LANG is the language you wish to return the descriptions in (this parameter is optional and not including it removes the name and description fields from the results). en is for English.
In the response is a listing of all of the achievements in the game.
{
"apiname": "TF_MVM_PYRO_BOMB_RESET",
"achieved": 0,
"name": "Hard Reset",
"description": "As a Pyro, reset the bomb 3 times in a single wave."
},
{
"apiname": "TF_MVM_ENGINEER_ESCAPE_SENTRY_BUSTER",
"achieved": 1,
"name": "Real Steal",
"description": "As an Engineer, escape with your sentry as a sentry buster is about to detonate."

I am creating my first AddOn using Quickbooks POS AddOn Dev Kit v10.
I have created a button in the receipts side buttons panel.
Now what I want is the current sales receipt.
For that, what I am trying to do is to get TxnID and query request processor, with that TxnID to get the whole receipt.
I have managed to get information like Qty, Desc1, ItemNum etc. I have also get the Receipt Schema.
https://idnforums.intuit.com/messageview.aspx?catid=49&threadid=16722
From above url, it says DocSID is the TxnID, but I cant get the field value through DocSID.
How can I get the TxnID or is there a better way to do it for getting the current sales reciept?
Thanks in Advance.
After working on it for 2-3 days, I came to know that TxnID will be created after the sales receipt is saved in QB POS through the IPOSService ProcessQBPOSXMLRequest method.
ProcessQBPOSXMLRequest only takes and repond in XML format. I created the receipt request in XML and send it ProcessQBPOSXMLRequest for processing.
I was avoding creatingg the XML request, since it was a long and tedious work, but I did similar work while creating another application with QBPOS SDK v3, with QBPOSFC3 library. I copied the code and add reference to QBPOSFC3.dll, and created xml from IMsgSetRequest interface which send request to POS request processor and convert the request in XML format.
I'm trying to read the data off a contactless Visa Paywave card.
For the Paywave, I have to submit a SELECT using PPSE (2PAY.SYS.DDF01) instead of PSE (1PAY.SYS.DDF01).
The EMV book 1, section 11.3.4, table 43 only describes how to interpret the response for a successful SELECT command using PSE. Does anyone know or can refer me to a source that shows how to process the data returned from a successful SELECT command using PPSE?
Here's my request APDU:
00A404000e325041592e5359532e444446303100
Here's the response:
6F2F840E325041592E5359532E4444463031A51DBF0C1A61184F07A0000000031010500A564953412044454249548701019000
I understand tag 84, tag 85, tag BF0C from the response. According to the examples for reading PSE, I should be able to just send GET PROCESSION OPTIONS (to get the AIP and AFL) with PDOL = null after this successful response as follows: 80A80000830000.
But request 80A80000830000 returns error code 6985 - Command not allowed; conditions of use not satisfied.
I also tried reading all the files after successfully selecting the PPSE by traversing through every single SFI (0-30) and every single record (0-16) of each SFI. Yes, I also did the 3 bit shift and bitwise-OR the SFI with 0x4. But I got no data.
I'm stuck, any help that would point me into getting some info from my Paywave card would be appreciated!
Have you tried this tool from EMVLAB http://www.emvlab.org/emvtags/
Using that tool,
http://www.emvlab.org/tlvutils/?data=6F2F840E325041592E5359532E4444463031A51DBF0C1A61184F07A0000000031010500A564953412044454249548701019000
2PAY.SYS.DDF01 is for contactless (e.g. NFC ) cards, while 1PAY.SYS.DDF01 is for contact cards.
After successfully (SW1 SW2 = 90 00) reading a PSE, you should only search for the SFI (tag 88) which is a mandatory field in the FCI template returned.
With the SFI as your start index, your would have to read the records starting from the start index until you get a 6A83 (RECORD_NOT_FOUND). E.g. if your SFI is 1, you would do a readRecord with record_number=1. That would probably be successful. Then you increament record_number to 2 and do readRecord again. The increament to 3 .... Repeat it until you get 6A83 as your status.
The records read would be ADFs (at least 1). Then your would have to compare the read ADF Names with what your terminal support and also based on the ASI (Application Selection Indicator). At the end you would have a list of possible ADFs (Candidate list)
All the above steps (1-3) are documented in chapter 12.3.2 Book1 v4.3 of the EMV spec.
You would have to make a final selection (Chapter 12.4 Book1)
Read the spec book 1 chapter 12.3 - 12.4 for all the detailed steps.
You seem to have the flow mixed up a bit, you want to:
Send 1PAY or 2PAY, it doesn't actually matter for all of the cards I've tested. This will return a list of the AIDs available on the card. Alternately you can just select an AID straight away if you know it's there but good practice would be to check first.
Get the list of AIDs returned in response to 1PAY/2PAY, in PayWave's case this will probably be A0000000031010 if you sent 2PAY but you may get more if you send 1PAY.
Select one of the AIDs sent back (or one you already know is on there).
Then loop through the SFIs and records sending the Read Records command to get the data.
You don't have to send Get Processing Options before sending the Read Records command even though that's now a normal transaction flow goes.
I think the information you're looking for is available from this VISA website. But only if you're a registered and/or licensed partner of VISA.
EDIT: Looking at the resulting TLV struct under BF0C:
tag=0xBF0C, length=0x1A
tag=0x61, length=0x18
tag=0x4F, length=0x07, value=0xA0000000031010 // looks like an AID to me
tag=0x50, length=0x0A, value="VISA DEBIT"
tag=0x87, length=0x01, value=0x01
I would guess that you need to first select A0000000031010 before getting the processing options.
I was selecting application 2PAY.SYS.DDF01. when I should have been selecting AID = 0xA0000000031010. It looks like there's no records under application 2PAY.SYS.DDF01.
But there was 1 record under application 0xA0000000031010. After I got this application, I performed a READ RECORD, and the first record gave me the PAN and all the credit card info I wanted.
Thanks everyone for chiming in.
