Developers
Build on Online Waiver Software
A plain JSON API and signed webhooks for connecting a point of sale, booking system or CRM. API access comes with the Growth plan and above.
What you can build
Signing links
Create a personal link with the person's details filled in and your own reference attached, then show it as a QR code or send it by email.
Who is covered
Look up a customer and ask whether their waiver is current before you sell them the activity.
Signings and PDFs
Read signed waivers, filter and page through them, and download the signer's copy as a PDF.
Webhooks
Get a signed message the moment a waiver is signed, a customer is added, or a link is opened.
Two ways to use it
You are a partner
You build software that many Online Waiver Software customers use. Apply for partner access, test in a sandbox, and let customers connect their account to your product in a few taps.
Partner programYou work for a customer
You connect one business to its own systems. The owner creates a key in Settings, or invites you to do it, and you are calling the API in minutes.
