HI,

1. Make sure the mappings are correct .

2. Check the API whether parameters have been passed or not.

3. Check the security for the service account.

Hi, thanks for your reply

I just created a web api with the default template start process and called the process model. Here we don't need to map any parameter.

Can you share the code in API.

Are you passing the body correctly that will match the Process parameters.

I think the data is not passed properly into the start process
