Hi, community! I’ve noticed that in some purchase order queries, the id of the PO and the po\_id that appear in the line items fields didn’t match, and the same for po\_number (that is empty) and vendor\_id. Request ID: “605b1de7587592ddcdc7dfbd” If you can provide me more info about this topic, it would be a great help! Thanks in advance, Eduardo ---

Hi @Eduardo Thanks for pointing that out! That might be because there are some IDs that are Base64 encoded, for example: _ **UHVyY2hhc2VPcmRlcjo1MTk0ODg=** _ Is [the encoded version](https://www.base64decode.org/) of _ **PurchaseOrder:519488** _ (Same for Vendor ID) po\_numer on the line\_item level is returning empty, we will see if we can fix that, but in the meantime using the po\_number at the PO level should work for this purpose ``` query { purchase_order(id: "UHVyY2hhc2VPcmRlcjo1MTk0ODg=") { request_id complexity data { id po_number } } } ``` Please let us know if that doesn’t help. Thanks in advance! Tom ---

Hi @tomasw ! Thanks for your reply I got it, but the vendor\_id of the PO could be useless if we have some line items provided by differents vendors, so we need the vendor\_id inside line\_item connection. Would it be possible for all IDs to have the same structure (encoded or not)? If this changes, it complicates the processing of data from different connections. And thanks for your tip to catch the po\_number and ID from PO level! ---

Hi @Eduardo ! My apologies for the delayed response! And I’m glad that tip helped! As for the po\_id its should be with the same format for all line items, something like this: “vendor\_id”: “319718”, And then on the Vendors Query: ``` query { vendors { request_id complexity data(first: 10) { edges { node { id legacy_id name email } } } } } ``` legacy\_id should match the “vendor\_id”: “319718”, for that vendor Let me know if I might be getting that wrong Thanks again!

Thanks @tomasw! But why this connection is using the legacy\_id? I thought it was deprecated. Is there any other connection where the legacy\_id is still active? I’ve been using the vendor\_id without any problem until few weeks ago so it seem to me to have been a recent change. Exists any post or web where we can follow the changes/updates in your GraphQL API? It could be a great help. Thanks in advance! Eduardo ---

Hi @Eduardo We apologize for that! it looks like there was a change on the backend of the Public API that might have impacted this. Would you like for us to switch it to UUID? > [@Eduardo](#): > > I’ve been using the vendor\_id without any problem until few weeks ago so it seem to me to have been a recent change. Exists any post or web where we can follow the changes/updates in your GraphQL API? It could be a great help. We should be keeping you updated on the changes and format changes like this one should not take place so again we apologize for that. Thanks again and please let me know if you need us to switch this ID format Tom ---

Hi @tomasw, don’t worry about that! And yes, please, it will be better for me to use the UUID so I could have the same type of identifier on all connections. > [@tomasw](#): > > Would you like for us to switch it to UUID? Thanks for all! ---

Perfect! Thanks @Eduardo. We will let you know as soon as this gets worked on
