Adding Profile Photos for multiple records

@Venky Immadisetty
Blackbaud does not have function for image convert to base64 as this is not specific to Blackbaud API. Any coding platform: Power Automate, PHP, Java, C#, etc has the functionality to convert an image to base64 string.

However, your understanding of this is incorrect.

The docuemnt_id and thumbnail_id request body to update a constituent profile picture is not sending the image as base64 string, it is the document location id for the image and thumbnail.

This is similar to uploading a “physical” attachment to constituent or gift record, you have to follow a few steps process first to get the “docuemt location” created in Blackbaud environment, then upload the image using HTTP PUT method onto this document location (identified by “UUID”, which is a 36 characters ID as highlighted above). Then use the PATCH API to update constituent profile picture by pointing the profile picture document_id to the document location UUID.

Thank you for your reference post; I used it as a guide. I am passing the HTTP headers as shown below.

I got the following error
Action 'HTTP' failed: The response to partial content upload request is not valid. The status code returned in the subsequent partial content response is 'Created'. Expected status code is 'OK'.
When Trouble shooting I understand that the Content Length of Create a document location action is 927

and the SharePoint image Content-Length is 4916

is this because of the content length? or something else? what should I have to do in order to resolve this error
Thank you!

Actual I am Passing the URI in the flow but its not in the screenshot. I ran the flow by removing the content length and again the same error
The response to partial content upload request is not valid. The status code returned in the subsequent partial content response is 'Created'. Expected status code is 'OK'.

Thanks!

Thanks @Alex Wong
I turned off Allow Chunking under setting in HTTP Action and the flow successfully updated the profile picture.

Thanks to Austin. She suggested to look up the error in the Microsoft power platform community.

Thank you!
