# Authenticate (verify) with typing pattern using Postman

If you have previously saved a typing pattern for a user, you can now authenticate by using the /verify Authentication API endpoint. See down below how to authenticate a user with a typing pattern.

_Import the TypingDNA Postman collection_

_Need help? Follow step 1-2 from [this tutorial](/content/docs/how-to-make-first-APIcall-postman.html)._

1. Click the **Collections** tab, then click the **TypingDNA Authentication API** collection.

2. Click the **Verify typing pattern** API service from the collection.

3. Click the **Body** tab.

4. Change the value of the **id** parameter (a string that identifies the user, min 6. chars). We used **testuser** for the purpose of this demo.

_Note: In order to authenticate, the user has to have a previously [saved typing pattern](/content/docs/save-typing-patterns-using-postman.html)._

5. Add a recorded typing pattern in the **tp** parameter. You can use this typing pattern as an example:

_0,2.12,0,0,18,1473785675,4,82,13,0,-1,-1,0,-1,-1,12,93,24,0,-1,-1\|8330,137\|1121,142\|902,144\|776,128\|792,51\|784,111\|864,151\|872,111\|824,127\|816,104\|888,95\|800,151\|808,119\|897,134\|775,101\|848,111\|1000,143\|688,126_

_Typingdna patterns are outputted by the [TypingDNA Authentication API JavaScript recorder](https://api.typingdna.com/docs/index.html#api-capture-class) on your front-end application. [Use this type-to-output tool to easily](/content/docs/typing-pattern-viewer.html) get typing patterns._

6. Click the **Send** button to make the Authentication API call. Now you should get a successful Authentication API reply.

_Reminder: To authenticate/verify a typing pattern, you have to previously [save a typing pattern](/content/docs/save-typing-patterns-using-postman.html) for the same user._

Congratulations. You have successfully managed to authenticate a typing pattern.
