@hundreds-queen-22353 For us it's the same agreement for everyone with a few variables that change. So we collect the data in Stacker from the user, automate creating the agreement in esignatures by using a template and values for each necessary variable, and store the URL to view/sign in Airtable. Then use that to display as the embed.
Esignatures does enable multi-person agreements. You can indicate who most sign first and second. We typically use this when we need our organization to counter sign. So we generate the agreement, have the user sign it, and then we usually automatically sign our side. You can also have it send an email to the second person to sign.
If your agreements are substantively different from user to user your process would need to be a little different. Esignatures might not be the best solution if you're not using any sort of template agreement.
