Add-ons

Warning

These v3 APIs are now deprecated and you should switch to a newer version before it is removed. See the API versions available for details of the different API versions available and the deprecation timeline.

Note

The only authentication method available at the moment is the internal one.

Autocomplete

Similar to add-ons search endpoint above, this endpoint allows you to search through public add-ons. Because it’s meant as a backend for autocomplete though, there are a couple key differences:

  • No pagination is supported. There are no next, prev or count fields, and passing page_size or page has no effect, a maximum of 10 results will be returned at all times.

  • Only a subset of fields are returned.

GET /api/v3/addons/autocomplete/
Query Parameters:

  • q (string) – The search query.

  • app (string) – Filter by add-on application availability.

  • appversion (string) – Filter by application version compatibility. Pass the full version as a string, e.g. 46.0. Only valid when the app parameter is also present.

  • author (string) – Filter by exact author username.

  • category (string) – Filter by category slug. app and type parameters need to be set, otherwise this parameter is ignored.

  • lang (string) – Activate translations in the specific language for that query. (See translated fields)

  • tag (string) – Filter by exact tag name. Multiple tag names can be specified, separated by comma(s).

  • type (string) – Filter by add-on type.

Detail

Language Tools

This endpoint allows you to list all public language tools add-ons available on AMO.

GET /api/v3/addons/language-tools/

Note

Because this endpoint is intended to be used to feed a page that displays all available language tools in a single page, it is not paginated as normal, and instead will return all results without obeying regular pagination parameters. The ordering is left undefined, it’s up to the clients to re-order results as needed before displaying the add-ons to the end-users.

In addition, the results can be cached for up to 24 hours, based on the full URL used in the request.

Query Parameters:

  • app (string) – Mandatory. Filter by add-on application availability.

  • appversion (string) – Filter by application version compatibility. Pass the full version as a string, e.g. 46.0. Only valid when both the app and type parameters are also present, and only makes sense for Language Packs, since Dictionaries are always compatible with every application version.

  • lang (string) – Activate translations in the specific language for that query. (See translated fields)

  • type (string) – Mandatory when appversion is present. Filter by add-on type. The default is to return both Language Packs or Dictionaries.

  • results[].id (int) – The add-on id on AMO.

  • results[].current_compatible_version (object) – Object holding the latest publicly available version of the add-on compatible with the appversion parameter used. Only present when appversion is passed and valid. For performance reasons, only the following version properties are returned on the object: id, files, reviewed, and version.

  • results[].name (string|object|null) – The add-on name (See translated fields).

  • results[].guid (string) –

    The add-on extension identifier.

  • results[].locale_disambiguation (string|null) – Free text field allowing clients to distinguish between multiple dictionaries in the same locale but different spellings. Only present when using the Language Tools endpoint.

  • results[].slug (string) – The add-on slug.

  • results[].target_locale (string) – For dictionaries and language packs, the locale the add-on is meant for. Only present when using the Language Tools endpoint.

Compat Override

This endpoint allows compatibility overrides specified by AMO admins to be searched. Compatibility overrides are used within Firefox i(and other toolkit applications e.g. Thunderbird) to change compatibility of installed add-ons where they have stopped working correctly in new release of Firefox, etc.

GET /api/v3/addons/compat-override/
Query Parameters:

  • guid (string) – Filter by exact add-on guid. Multiple guids can be specified, separated by comma(s), in which case any add-ons matching any of the guids will be returned. As guids are unique there should be at most one add-on result per guid specified.

  • results[].version_ranges[].applications[].guid (string) – Application guid.

Recommendations

This endpoint provides recommendations of other addons to install, fetched from the recommendation service. Four recommendations are fetched, but only valid, publicly available addons are shown (so max 4 will be returned, and possibly less).

GET /api/v3/addons/recommendations/
Query Parameters:

  • guid (string) – Fetch recommendations for this add-on guid.

  • lang (string) – Activate translations in the specific language for that query. (See translated fields)
