API Question - collect transaction IDs from multiple vendors and submit them together

[abqdigital]

Use case:

If I had an event with 2 different vendors, both using square POS, can the API support software with the following general spec:

• customer receives product from vendor 1
• vendor 1 submits API call with transaction ID (or temporary pre-transaction ID) to central database
• customer receives product from vendor 2
• vendor 2 submits API call with transaction ID to central database
• customer approaches central payment processing point and their transactions IDS are brought up and submitted either
  • 1) as a group; or 
  • 2) in a series
• payment is processed 

Any advice or current thoughts/solutions greatly appreciated.

Thanks for joining the Seller Community @abqdigital!

At this time there isn't a way to process a group of transactions, and I'm afraid it's also not possible to have multiple vendors contribute to an open order that can be processed with a single API call. I've shared this request with the API team.

Thanks - this is an important feature for event software we're designing.  Is there a way I can get in touch with an API developer and run some potential workarounds/solutions by them?  if we develop outside software that builds an array of orders and them submits them at once to Square via multiple vendors, is that a potential solution?

Would be great to be in touch with someone technical - thanks so much

Of course! You can contact the API Customer Success team directly and they'll be happy to help you with any available workarounds. Thanks for your patience!
