Integration
Connect HelloSign and OptiPub
When New Signature Request fires in HelloSign, your agent runs Add Email to Segment in OptiPub, or Feedback Loop in OptiPub to Get Signature Request Files in HelloSign. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.

Questions
HelloSign and OptiPub, answered
What can start an automation from HelloSign?
Any of HelloSign's 1 trigger in the catalog, including New Signature Request. Describe the moment in plain language and your agent picks the right one.
What can your agent do in OptiPub when something happens in HelloSign?
Any of OptiPub's 8 actions, including Create Resource, Create Subscription, Send Email and Add Email to Segment. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from OptiPub to HelloSign?
Yes. When something happens in OptiPub, your agent can act in HelloSign too. This page covers both directions: OptiPub's triggers and HelloSign's actions are listed here as well.
Do I have to build a connector for HelloSign or OptiPub?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use HelloSign and OptiPub without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
