Hi @daryldiaday,

Refer to the example available in the following help article,

The step in short,

  1. Do a GET request for the Bill to which you need to attach the file
  2. From the response in the step 2, use the URL from the files field available under the _links entity to attach the file

Feel free to post if you have any questions. Good Luck,

Hi Rohit/Vignesh,

Thank you for the responses.

I have questions regarding the links you’ve provided as there are 2 different ways to attach files to the record:

for this specific article, it’s using the files:put “URL” for the next request to attach the file.


While this article,

using a different PUT URL request:


Are these 2 requests valid and just the same?

Hey @daryldiaday,

If you are using or extending the Default endpoint 22.200.001 and above, I would suggest you use the _links approach. As far as, I remember, these are functionalities introduced in Default endpoint 22.200.001. 

If you are using the 20.200.001 and below version, you can use the approach suggested by @RohitRattan88. Hope that clarifies.!
