Evaluate sealing in six clear steps
Create an account, generate a free test API key, and run an end-to-end seal in minutes. This path is designed for developer and product teams validating fit before production rollout.
Process guide
Step-by-step technical eval
Follow this exact sequence to validate API access, local sealing behavior, and Acrobat results before moving to trusted production certificates.
Step 1
Create an account
Create your Trusted Signatures account to access API credentials and evaluation tooling.
Step 2
Create a test API key
Generate a free test key. This enables sealing with an untrusted certificate and requires no credit card.
Step 3
Install CLI or Zap
Choose the integration path that matches your workflow: command line for engineering pipelines or Zapier for automation.
Step 4
Configure with your API key
Follow documentation to set key ID and key secret in your selected toolchain.
Step 5
Seal a document
Run a seal operation using your test key and verify your output PDF is generated without uploading source documents.
Step 6
Open in Acrobat
The document will be sealed but not trusted yet. In this test mode you should not expect the blue badge or green check.
How it works
Seal and verify workflow
Use this model during technical evaluation to validate the sealing path and reader verification behavior end-to-end.
Seal PDF
- Send a request using CLI/API/Zap to Trusted Signatures (no document upload).
- Embed the returned seal into the PDF.
- Distribute the sealed PDF.
Verify PDF
- Open the PDF in a reader or use Trusted Signatures Validator.
- The seal is verified automatically and the sealer name is displayed.
