The Addo API documentation describes Addo Sign web service and explains how to integrate with it. The integration to Addo Sign is via Rest API.

If desired, a developer resource can be contacted if you have questions or need help with the API integration. This is usually free of charge, but Visma reserves the right, by prior agreement, to invoice part of the time spent on larger projects.

After the development has been completed on the demo environment, a similar environment can be created with integration user on production.

Note: In order to generate a token to use the API, you must log in with your login information. In addition, your password must be SHA-256 and then base 64 encrypted, which can be done via this link: https://hash.online-convert.com/sha512-generator
