set_search_channel_locations

Set the geographic targeting of a wizard campaign's search channel (Google Ads or Microsoft Ads) — which countries/states the campaign serves in, and which countries to exclude.

                Matches the platform UI's "Location" picker under the Google Ads / Microsoft Ads channel SETTINGS panel, plus the "Negative Locations" editor under that channel's Advanced Settings.

                ⚠️ NEW SEARCH CAMPAIGNS DEFAULT TO UNITED STATES. The platform seeds the Location
                field with United States, so a campaign created without calling this tool serves in
                the US only. Whenever the user names a geography — "target Canada and the UK",
                "run this in EMEA", "exclude India" — set it explicitly; do not assume the default
                is what they want.

                WHEN TO USE:
                - Point a search campaign at specific countries/states instead of the US default
                - Exclude countries the campaign must not serve in
                - Clear targeting back to all locations (countries=[], states=[])

                REQUIREMENTS:
                - The campaign MUST already have the target channel enabled (via create_campaign /
                  add_and_edit_campaign_elements with a `google` and/or `microsoft` block).
                - Geo targeting here is search-channel-only. LinkedIn / Meta / Reddit carry location
                  on the audience or target group instead — use create_target_group or the audience
                  tools for those.

                PARAMETERS (each one REPLACES that side of the targeting; omit to leave untouched):
                - campaign_id (required): the wizard campaign ID.
                - channel (required): "GOOGLE_ADS" or "MICROSOFT_ADS".
                - countries: country NAMES to target, e.g. ["United States", "Canada"].
                  Pass [] to clear (= all locations).
                - states: US state NAMES to target, e.g. ["Texas", "California"].
                  Pass [] to clear. States are US-only.
                - excluded_countries: country NAMES the campaign must NOT serve in.
                  Pass [] to clear all exclusions.

                Names are matched case-insensitively against the platform's location catalog and
                common shorthand resolves ("USA", "UK", "UAE"). An unrecognised name is REJECTED
                rather than skipped — a silently dropped geo would serve the campaign somewhere
                nobody chose. At least one of the three lists must be given.

                ⚠️ EXCLUSIONS ARE COUNTRY-LEVEL ONLY. The platform stores exclusions as bare
                location ids with no country/state discriminator, and state ids overlap country ids,
                so an excluded state would be read back as an unrelated country. The UI's Negative
                Locations picker is countries-only for the same reason. To narrow within a country,
                target the states you want via `states` instead of excluding the ones you don't.

                EXAMPLES:

                Target Canada and the UK on Google Ads (replacing the US default):
                set_search_channel_locations({
                    "campaign_id": 177214,
                    "channel": "GOOGLE_ADS",
                    "countries": ["Canada", "United Kingdom"]
                })

                Target three US states only:
                set_search_channel_locations({
                    "campaign_id": 177214,
                    "channel": "GOOGLE_ADS",
                    "countries": ["United States"],
                    "states": ["Texas", "California", "New York"]
                })

                Keep targeting as-is but exclude two countries on Microsoft Ads:
                set_search_channel_locations({
                    "campaign_id": 177214,
                    "channel": "MICROSOFT_ADS",
                    "excluded_countries": ["India", "Pakistan"]
                })

                RESPONSE: {success, campaign_id, channel_id, channel, applied:{locations?:{countries,states}, excluded_locations?:{countries}}, errors?}
                `applied` echoes the resolved location NAMES, so you can confirm back to the user what the campaign now targets.

                INTEGRATION WITH OTHER TOOLS:
                - Use search_campaigns_by_names / get_campaign_by_wizard_id to find the campaign.
                - create_campaign and add_and_edit_campaign_elements accept the same geo inline on
                  their `google` / `microsoft` blocks — prefer that when creating, and use this tool
                  to change geo on a campaign that already exists.
