Now that we can add records to the Dataverse, the next logical step is to update those existing records.

In this scenario, we have a record that already exists so we are going to use the PATCH protocol to update our record. As this record already exists, we are going to be appending our as a Template Parameter (similar to when we searched for a particular record).

You can use the same payload infrastructure you used when we were adding a record since any reference to your record ID is not included in the payload.

Where things differ is within the Update method itself. As we are following the Dataverse Web API URL structure, you need to append the ContactId parameter in the same way you would if you were updating the record. Therefore this includes using the rewrite-uri template in a similar fashion as provided below.

Once complete, you can validate your function using the “Test” function.

And when complete you should have a newly updated record in PowerApps.
