Postman API

postman api

The Postman API allows you to programmatically access data stored in Postman account with ease.

The easiest way to get started with the API is to click the Run in Postman button present at the top of the documentation page and use the Postman App to send requests.


  1. You need a valid API Key to send requests to the API endpoints. You can get your key from the integrations dashboard.

  2. The API has an access rate limit applied to it.

  3. The Postman API will only respond to secured communication done over HTTPS. HTTP requests will be sent a 301 redirect to corresponding HTTPS resources.

  4. Response to every request is sent in JSON format. In case the API request results in an error, it is represented by an "error": {} key in the JSON response.

  5. The request method (verb) determines the nature of action you intend to perform. A request made using the GET method implies that you want to fetch something from Postman, and POST implies you want to save something new to Postman.

  6. The API calls will respond with appropriate HTTP status codes for all requests. Within Postman Client, when a response is received, the status code is highlighted and is accompanied by a help text that indicates the possible meaning of the response code. A 200 OK indicates all went well, while 4XX or 5XX response codes indicate an error from the requesting client or our API servers respectively.

  7. Individual resources in your Postman Account is accessible using its unique id (uid). The uid is a simple concatenation of the resource owner's user-id and the resource-id. For example, a collection's uid is {{owner_id}}-{{collection_id}}.


An API Key is required to be sent as part of every request to the Postman API, in the form of an X-Api-Key request header.

If you do not have an API Key, you can easily generate one by heading over to the Postman Integrations Dashboard.

An API Key tells our API server that the request it received came from you. Everything that you have access to in Postman is accessible with an API Key that is generated by you.

For ease of use inside Postman, you could store your API key in an environment variable called postman_api_key and this Collection will automatically use it to make API calls.

API Key related error response

If an API Key is missing, malformed, or invalid, you will receive a 401 Unauthorised response code and the following JSON response:

  "error": { 
    "name": "AuthenticationError",
    "message": "API Key missing. Every request requires an API Key to be sent."

Using the API Key as a query parameter

Every request that accepts API Key as X-Api-Key request header, also accepts the key when sent as apikey URL query parameter.

API key sent as part of the header has a higher priority in case you send the key using both request header and query parameter.

Rate Limits

API access rate limits are applied at a per-key basis in unit time. Access to the API using a key is limited to 60 requests per minute. In addition, every API response is accompanied by the following set of headers to identify the status of your consumption.

Header Description
X-RateLimit-Limit The maximum number of requests that the consumer is permitted to make per minute.
X-RateLimit-Remaining The number of requests remaining in the current rate limit window.
X-RateLimit-Reset The time at which the current rate limit window resets in UTC epoch seconds.

Once you hit the rate limit, you will receive a response similar to the following JSON, with a status code of 429 Too Many Requests.

  "error": {
    "name": "rateLimitError",
    "message": "Rate Limit exceeded. Please retry at 1465452702843"

In the event you receive a 503 response from our servers, it implies that we have hit an unexpected spike in API access traffic and would usually be operational within the next 5 minutes. If the outage persists, or your receive any other form of 5XX error, kindly let us know.
