# Supplier API (ZAPI) ### Purpose of this Document We provide this API for those developers and organizations who wish to perform a deeper integration to a single instance of the platform, not offered in the other APIs. Use cases for this type of integration might be with internal CRM's, HR, payroll, accounting system. Before considering this level of integration, it's likely that most integrations can be achieved though a combination of Webhooks + Zapier -> Your system. We encourage you to consider this before committing to the level required for the ZAPI spec. If you're not certain which API to consider for your project then contact our team and we would be happy to have a discussion about your integration requirements. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
