C2PA Zapier Integration: No-Code Content Signing
Definition: The Original Pictures Zapier integration lets non-technical teams call the signing API from a Zap, so content flowing through an automation is signed without writing code.
TL;DR: Zapier connects thousands of apps for millions of users. A Webhooks action that POSTs a file to the signing API drops provenance into any no-code workflow, from form uploads to cloud-storage triggers.
Signing in a Zap
Add a Webhooks by Zapier action that POSTs the file from a previous step to the signing API with your key and watermark and anchor flags. The response carries the manifest and verify URLs, which later steps can store or send.
Who this is for
Marketing, operations, and content teams who automate with Zapier but do not write code. They can add signing to existing Zaps, such as new file in Drive then sign then post, without engineering involvement.
Limits
No-code is great for moderate volume and simple flows. For high throughput or tight latency, move to a direct API integration or the AWS or Next.js patterns; the same API backs all of them.
Implementation
Zapier Webhooks action (POST): URL: https://api.originalpictures.com/v1/sign Headers: Authorization: Bearer {{OP_API_KEY}} Data (multipart): asset={{file}}, producer={{org}}, watermark=trustmark, anchor=true Output: manifest_url, verify_url
FAQ
Is no-code secure for my key?
Store the key in Zapier's secure fields, not in plain steps. For sensitive or high-volume use, prefer a server-side integration.
Where Original Pictures stands today
Original Pictures ships three things today: a Sign API, a Verify API, and the SDKs that wrap them. One POST /v1/sign attaches a C2PA-format manifest, an invisible TrustMark watermark, and an OpenTimestamps anchor. The open-source verifier checks any of it without calling us.
Two things are on the near roadmap, and we name them as roadmap, not as shipped: C2PA Conformance Program recognition (target Q3 2026, until then our manifests use the published C2PA v2.2 format and any C2PA-aware validator can read them, but third-party validators will show our signer as not-yet-listed), and a consumer capture app (Q3 2026). We do not sell a capture SDK, and we do not claim Trust-List membership we do not yet hold.
Bottom line: Add a Webhooks action that POSTs files to the signing API, and any Zapier automation gains provenance with no code.

Original Pictures is progressing through the C2PA Conformance Program; our signing certificate is not yet on the official C2PA Trust List. Target: Q3 2026. We will not describe ourselves as "C2PA-certified" until it is true.
