How to integrate e-signatures with HubSpot for Australian businesses?

To integrate e-signatures with HubSpot, first select a compatible e-signature provider with API support. Create a HubSpot developer account to obtain API keys. Use the provider's API to connect with HubSpot's workflows or deals API, enabling automated document sending upon trigger events like deal stage changes. Test the integration in a sandbox environment to verify data flow and signature capture. For Australian businesses, ensure the provider supports ESIGN-equivalent compliance under the Electronic Transactions Act 1999.
