# Onboarding
Ensure that the [Postscript Shopify App](https://apps.shopify.com/postscript-sms-marketing) is installed on your Shopify store before proceeding with the following steps.
### Obtaining the Shop API Key
Once you have installed the Postscript Shopify App, navigate to your [shop's API settings page](https://app.postscript.io/account/api). Click the **Create security key pair** button to generate a new API key pair:
Copy the **Private key** value that we'll use in the next step (it should look something like `sk_1234567890abcdef1234567890abcdef`).
### Adding the Postscript Channel
In your site's view page, add the Postscript channel and enter a name for the channel you're creating.
In the **Postscript Shop Token** field, paste the private key from the previous step and click **Save & Deploy**. You're now done adding Postscript!

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.edgetag.io/channels/postscript/onboarding.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
