To use SignRequest's Zapier integration you will need one of the paid plans. This can be either a Pro or Business plan.
If you're new to SignRequest and activate a Zapier integration you'll automatically be placed in a 30-day free trial. Depending on how many Zaps and the complexity of your steps, you can either use the free plan or upgrade to a paid plan. For more information on Zapiers pricing click here.
It is also possible to test Zapier by creating a Sandbox account. You can test with making as many Zaps as you wish. The only difference is that the final signed document will contain a visible watermark.
With every paid licence you can sent 30 documents through Zapier, irrespective of the number of pages / signers / documents.
If you need to send more documents you can upgrade to an API subscription. Please contact us for further details.
