# Create your test environment
For this stage, we will use Postman. You can download from this URL:
Once Postman is installed, you can configure it by creating a new environment:
* Click on `Environments` and then the `+` button
## Define the environment
Set a name for this environment. For example « ARCHIPELS CONNECT SANDBOX»
Set the variable Base\_URL with the available values:\
\- **Sandbox**: app-api.sandbox.archipels.io\
\- **Production**: app-api.archipels.io
* Create a second variable "AccessTokenHolder", and paste the value of the access token you created previously in [Configure an access token](/archipels-documentation/set-up/configure-an-access-token.md)
## Configure your wallet API collection
Create a new collection (this is where you will store all your calls). Click on `Collection`, click on the `+` button and select *`blank collection`*
* Set a name. For example « Archipels Connect collection Holder»
* Configure the authentication to get access to the API services
* Select the collection `Collection archipels Connect Holder` and click on the `Authorization` tab:
* Select the type: OAuth 2.0
* Enter the value of the following variable created in the environment: {{AccessTokenHolder}}. This variable will be automatically replaced by the value you defined in the environment.\
Save your configuration :tada:

For all the requests you will create in this collection, do not set an OATH authorization! Keep the default setting `Inherit auth from parent`:
{% endhint %}
