Primer

Start in Integrations on the Primer Dashboard and choose + New integration. Select a processor, connect its account using the requested credentials or authorization flow, and add the relevant merchant accounts. At least one processor must be connected before live payment processing.

Then open Workflows. A payment workflow can begin with the Payment created trigger and pass its payment identifier to an Authorize payment action using the chosen processor. Add conditions to select the appropriate route. Primer validates incomplete blocks before publishing; edits to a published workflow stay in a draft until you publish them again.

Inspect an actual Workflow Run to understand the result. Its timeline shows the route taken, and selecting a block reveals its inputs, outputs and requests. A completed workflow does not necessarily mean a paid order: a processor can decline a payment while the workflow itself finishes normally. Conversely, a later notification failure can mark the run unsuccessful after authorization has already succeeded. Check the payment timeline as well.

Compare those transaction results before changing rules for later traffic. The commercial order form sets the service fees and any minimum commitment, so include both expected volume and the required connections when discussing the contract.
