Introduction

Integrate your external database into your Wix site using external collections and building an external database collection adaptor.

The External Database Collections service plugin (formerly SPI) describes the API requests your adaptor needs to expect from your Wix site, and the responses your Wix site expects in return. The service plugin takes the request from your Wix site and converts it into a request that your external database can receive. It also takes the response from the external database and converts it into a JSON response that your Wix site can receive.

You can learn more about working with External Databases on your Wix site here.

Mandatory Endpoints

The following endpoints are mandatory and must be implemented in your adaptor. All other endpoints are optional.

EndpointFunction

Find ItemsGet a list of items based on a filter.
CountGet the number of rows or items in a table or collection based on a filter.
ProvisionEstablish the connection between your site and your adaptor.

The implemented endpoints must be exposed via the schema object in the allowedOperations list.

Data Structures

_id

Each table or collection must contain an _id column or attribute of type string. If you create new data outside of your Wix site, or you are importing new data for use with your site, you must populate this field with a unique value. If you create new data in your site, the Wix Data backend will generate a unique 36-character UUID for each item created. The _id attribute can be any length but if items are created by your Wix site, it must be at least 36 characters long.

_owner (optional)

For data created by your Wix site, Wix Data backend will populate the _owner attribute with a 36-character UUID identifying the user who created the data. If the visitor is not a logged-in member, the _owner attribute is based on a browser cookie and is therefore consistent between sessions. The _owner attribute will be null if the new data was created by a backend process.

Dates

All dates must be an ISO string encapsulated in an object. For example: "myDate" :{“$date”:”2001-02-11T00:00:00.000Z”}
