### Introduction

Sometimes when trying to connect to an external API through Alumio, you may run into the issue. For example, when you make a GET request to the external API, the system returns a proper response but the body response can be empty.

This was caused by an inability to differentiate a user token as plain text in the response body. Therefore, here we are to provide you with more details on how you can solve the corresponding issue.

### Plain text response decoder

There are two common cases which can help you solve the issue when requesting the external API to return token as the plain text. Let’s have a look at them both!

**Case 1: Create a Route that uses an HTTP Subscriber.**

1. Use a URL that returns plain text.
2. Configure the “Plain text” response decoder.
3. Run the Incoming configuration.
4. Plain text is added as entity data in the configured key.

**Case 2: Create a Transformer with the Value mapper inside.**

- Use the pattern accessor. Configure a pattern.
- Add a Deserialize mapper.
  - Configure the plain text deserializer.
