We’re a SaaS company that builds platforms for our clients, and we’ve recently integrated with your API to allow our clients to send data from our platform into their own Salesforce instance.
Before connecting, we ask clients to provide us with their version number, object they’d like to connect to, and ID object so that we can match platform users to those in Salesforce. We then pull this data into the API call and send it to Salesforce. This works for all our clients, except one.
We are now trying to help one of our clients connect and coming across the following error: [{salesforce sync HTTP Method 'PATCH' not allowed. Allowed are HEAD,GET,POST"}]
The client has confirmed that the version number, object and ID are correct, but continue to get this error.

Does anyone have any ideas?
