Overview
The fastest way to explore and test RB2B APIs is through our interactive Postman workspace at https://postman.api.rb2b.com/
This workspace includes all available RB2B API endpoints, preconfigured request examples, and built-in authentication fields — allowing you to make live API calls without writing code.
Before You Begin
Before testing any RB2B API endpoints, make sure you have:
An active RB2B APIs account
Your API key (found under API Keys in your dashboard)
At least 100 credits available (purchased during registration or from the Billing page)
💡 Tip: If you haven’t signed up yet, see Registering for RB2B APIs for instructions.
Step 1: Open the RB2B APIs Postman Workspace
Visit https://postman.api.rb2b.com/ to open the RB2B APIs public workspace.
You can:
Explore endpoints directly in your browser, or
Click “Run in Postman” to open the collection in your local Postman app.
Step 2: Set Your API Key
In Postman, open the RB2B APIs collection.
Navigate to the Variables tab.
Locate the variable named
api_key.Paste your RB2B API key as the value.
Click Save.
Your key will automatically populate the Authorization header in all sample requests.
⚠️ Important: Your API key is private. Do not share it publicly or embed it in client-side code.
Step 3: Choose an Endpoint to Test
Within the collection, you’ll find all available endpoints grouped by category — such as Identification and Enrichment APIs.
Example endpoints include:
IP to HEMHEM to Business ProfileIP to Company
Click any endpoint to view its:
URL and HTTP method
Required parameters and body examples
Sample responses and schema
Step 4: Send a Test Request
Select an endpoint (for example, IP to HEM).
Switch to the Body tab and edit the sample input as needed.
Example:{ "ip_address" : "{{ip_address}}" }Click Send to execute the request.
If your key and parameters are valid, you’ll receive a JSON response with your result data.
Step 5: Review Your Results
Review your results in Postman and compare to the examples of the individual APIs' successful and empty responses as well as malformed requests.
