Loading records of object having two lookup fields on the same object(Contact)

@Mihir

I can see that this is related with the ContentVersion object in Salesforce(correct me if I am wrong).

Instead of using Rest Post Snap, check with the Salesforce Create Snap. The Snap supports the ContentVersion object.

I tried using Salesforce Create snap with ContentVersion object but it is has a limitation of uploading 50Mb of text file or 37Mb of binary file. But I have upload a file whose size can vary upto ~250Mb.

Thanks,
Mihir

@Mihir

I was not aware about that limitation. Did the snap fail if you try to upload content greater than 50MB/37MB?

I am not very familiar with the Salesforce API’s, but you can try to send below sample as a body of the request (by replacing with your data):

{
    "ContentDocumentId": "069D00000000so2",
    "ReasonForChange": "Marketing materials updated",
    "PathOnClient": "Q1 Sales Brochure.pdf",
	"VersionData": "your binary file data(file content)"
}

And add Content Type = multipart/form-data, as a header of the request:
