I use a trial account to integrate sign api in my project until it launches.
I can able to send the document via email.
But when I tried to get an agreement, I faced an error like this;
message: 'The API caller does not have permission to execute this operation' }
how can I solve this issue?
My guess would be that you are not trying to "get" the agreement while you are impersonating the sender?
The x-api-user header parameter must be used to get the agreement while impersonating the same email address as was used to create the agreement.
