List the account's Google Ads / Microsoft Ads library extensions (sitelinks, callouts, snippets, etc.) with their internal ids.
Read extensions
Returns data. Calling it changes nothing, so it is safe in an unattended loop.
What it does
List the account's Google Ads / Microsoft Ads library extensions (sitelinks, callouts, snippets, etc.) with their internal ids.
ALSO KNOWN AS: list extensions, show extensions, find sitelink, which extensions do we have, extension library, browse extensions
KEYWORDS: list, show, find, browse, extensions, sitelink, callout, library, google ads, microsoft ads, bing, id
WHEN TO USE:
- "What sitelinks do we have?" / "Show our Google Ads extensions"
- ALWAYS before add_extensions_to_native_campaign or remove_extensions_from_native_campaign — those need internal ids, and this is the only tool that returns them. The create_*_extension tools return an empty body and cannot tell you the new id.
WHEN NOT TO USE:
- Creating a new extension → use the relevant create_*_extension tool
- Non-search channels (Facebook / LinkedIn / Reddit) — extensions do not exist there
INPUTS:
- channel (required): GOOGLE_ADS or MICROSOFT_ADS
- types (optional): filter, e.g. ["SITELINK"]
- name (optional): name filter. Extension names are AUTO-DERIVED, not user-chosen — a sitelink's name is its link text and both description lines joined by newlines, truncated to 50 chars. Filter by `types` and match on the returned fields instead of guessing a name.
- page / size (optional): pagination, defaults 0 / 50
Returns {totalElements, totalPages, data:[{id, name, type, createdDate, ...}]}. Only campaign-attachable extensions are listed (account-level ones are excluded by the platform).Arguments
| Argument | Type | Notes | |
|---|---|---|---|
channel |
string | required | Search channel. Ad extensions are a search-channel-only concept. one of: GOOGLE_ADS, MICROSOFT_ADS |
types |
array | Optional extension-type filter, e.g. ["SITELINK"]. | |
name |
string | Optional name filter. Names are auto-derived by the platform, not user-chosen, so prefer filtering by `types`. | |
page |
integer | 0-based page index. Defaults to 0. | |
size |
integer | Page size. Defaults to 50. |
Request
Request template, not a complete runnable example. Replace placeholders, empty objects, arrays, and zero values with valid account-specific inputs.
