Test the SignBolt API in Postman

SignBolt ships a ready-to-import Postman v2.1 collection covering every endpoint in our public REST API. Download it below, import into Postman, hit the sandbox request, and you'll get a signed PDF back in under 60 seconds — no signup, no credit card.

Import the collection in 4 steps

1
Download both Postman files
Save the collection and environment exports from the buttons above.
```
GET /postman/SignBolt.postman_collection.json
GET /postman/SignBolt.postman_environment.json
```
2
Import the files into Postman
Open Postman, import both JSON files, then select the SignBolt API environment.
```
Postman -> Import -> Files
Select:
- SignBolt.postman_collection.json
- SignBolt.postman_environment.json
```
3
Run the sandbox signing request
Start with the first request. It uses the public sandbox token and does not need a live API key.
```
POST {{baseUrl}}/api/v1/sandbox/sign
Authorization: Bearer {{sandboxToken}}
```
4
Add a production API key
When the sandbox request passes, paste your live key into the environment and run production requests.
```
apiKey=sb_live_your_key_here
POST {{baseUrl}}/api/v1/sign
Authorization: Bearer {{apiKey}}
```

Use cURL instead

Postman is best for shared collections. cURL is the fastest way to prove the public sandbox path from a terminal or CI job.

curl -X POST https://signbolt.au/api/v1/sandbox/sign \
  -H "Authorization: Bearer sb_sandbox_2026" \
  -H "Content-Type: application/json" \
  -d '{"document_url":"https://signbolt.au/sample.pdf"}'

Postman vs Insomnia vs Bruno vs cURL

Tool	Setup	Best fit	When to choose it
Postman	Import 2 JSON files	Team handoff, saved environments, request tests	Use it when a backend team needs shared examples and repeatable checks.
Insomnia	Recreate requests manually	Lightweight API debugging	Use it when one developer wants a local client with fewer workspace features.
Bruno	Convert or rebuild the collection	Git-tracked request collections	Use it when requests need to live beside source control as plain files.
cURL	Copy 1 command	CI smoke tests and terminal checks	Use it when you need the smallest possible test with no desktop app.

Postman FAQ

How do I import the SignBolt Postman collection?

Download the collection and environment JSON files, open Postman, choose Import, then select both files. Set the SignBolt API environment active before running the sandbox request.

Do I need an API key to test SignBolt in Postman?

No. The first request uses the public sb_sandbox_2026 token and returns a mock signing response without signup. Production requests need a live Bearer API key from the dashboard.

What's the difference between sandbox and production Postman environments?

Sandbox uses sb_sandbox_2026 and returns deterministic mock data. Production uses your sb_live key, processes real documents, and records signing metadata against your account.

Does SignBolt support Insomnia or Bruno?

Yes. SignBolt uses standard REST endpoints, Bearer auth, JSON, and multipart form data, so the same requests can be recreated in Insomnia, Bruno, or cURL.

Ready for production API signing?

Generate a live Bearer key from the dashboard, paste it into the Postman environment, then rerun the production signing request.
