Hi @Daniel Filho !
Regarding the report showing "multiple", this happens when the selected report shows the individual data of each envelopeID per line (like the Envelope Report). If you want a view of each recipient for each envelope in a different line, try using the Envelope Recipient Report.
In parallel, I’d like to suggest something simpler to check the envelopes. If you’re using an integration, normally all the envelopes are centralized in/sent by just one user, so you can use Share Access to access the sent box of this API user, and checl/take actions directly through the Agreements tab.
