# Get Google Ads metric trend

> <Info>This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.</Info>

Returns one metric as a time series for a date window, bucketed daily, weekly or monthly.

`metric` is one of `impressions`, `clicks`, `cost_micros`, `conversions`, `conversions_value`, `ctr`, or `average_cpc_micros`. Anything else is rejected with a 400.

`ctr` and `average_cpc_micros` are rates, so each bucket is computed from the underlying counts rather than by adding up the daily rates. A bucket with no impressions has a `ctr` of `0`, and one with no clicks has an `average_cpc_micros` of `0`.

`granularity` is `DAILY`, `WEEKLY` or `MONTHLY` and defaults to `DAILY`. Weekly buckets are anchored to Monday. Buckets with no activity are not returned, so expect gaps rather than zeroes.

An account with no synced campaigns returns an empty list.

<Note>These numbers come from Base44's own nightly copy of your Google Ads metrics, not from Google directly, so the last few hours of activity can be missing.</Note>

<Note>`start_date` and `end_date` are inclusive and must both be `YYYY-MM-DD`. Anything else is rejected with a 400.</Note>

<Note>This endpoint accepts a personal API key. Workspace API keys are not authorized for it and are rejected with a 403.</Note>

        Returns one metric as a time series for a date window, bucketed daily,
        weekly or monthly.


        `metric` is one of `impressions`, `clicks`, `cost_micros`,
        `conversions`, `conversions_value`, `ctr`, or `average_cpc_micros`.
        Anything else is rejected with a 400.


        `ctr` and `average_cpc_micros` are rates, so each bucket is computed
        from the underlying counts rather than by adding up the daily rates. A
        bucket with no impressions has a `ctr` of `0`, and one with no clicks
        has an `average_cpc_micros` of `0`.


        `granularity` is `DAILY`, `WEEKLY` or `MONTHLY` and defaults to `DAILY`.
        Weekly buckets are anchored to Monday. Buckets with no activity are not
        returned, so expect gaps rather than zeroes.


        An account with no synced campaigns returns an empty list.
