Click [Authorize with a workspace].
Give OC Rooster permission to access your Notion. You will be presented with a UI to select a page, please choose one. This will be changed later, so it doesn't matter what you choose.
<aside> 💡 In our service, the images read from Notion and the OCRed text will not be stored in OC Rooster system. Nor will it be used for anything else. The way it works is, we'll take the URL of the Notion image, run it through Google's OCR called Google Cloud Vision API, and return the results to you.
</aside>
Next, get the Database ID. In Notion, access via the API is allowed only on a per-database basis.
First, create the database (table) you want to OCR this time, or display an existing one.
The next step is to invite OC Rooster here and allow it to access the API. Click [Share] and then [Invite] to select the Integration and invite it.(Need [Can edit] or [Full access] permission)
Next, click [Copy link] in the window opened by [Share] to get the URL.
