Analytics query 400 on interactionId filter from webhook payload

General Discussion
1

Edge function catches routing.call.answered events and hits the Analytics API for agent metrics. It’s throwing 400 with Invalid filter expression. Payload matches the schema. Don’t see the error in the validator. Logs are doing jack all here.

  • Deno 1.42 on Deploy
  • GC API v2 /analytics/conversations/queries
  • Timezone: Asia/Seoul
const body = JSON.stringify({
 dateRange: { from: new Date().toISOString(), to: new Date(Date.now() + 86400000).toISOString() },
 filter: `interactionId IN (${id})`
});

Syntax rejects the IN clause for strings. Exact match works, but batch lookups fail. What’s the correct filter operator for multiple interaction IDs?

The 400 error typically originates from timezone boundary misalignment in the Analytics API. When webhook payloads inject interactionId filters alongside relative timestamps, the query engine doesn’t parse the hourly buckets correctly. Shift the dateRange to fixed ISO strings anchored to your reporting timezone. Historical forecasting models require strict bucket alignment to prevent statistical skew. Try this payload structure:

{
 "dateRange": { "from": "2024-01-01T00:00:00+09:00", "to": "2024-01-01T01:00:00+09:00" },
 "query": { "type": "filter", "typeFilter": "interactions", "filter": { "type": "equals", "field": "interactions.id", "value": "${interactionId}" } },
 "groupBy": ["interactions.type"]
}

Community posts from last quarter noted the validator drops trailing milliseconds in webhook timestamps, which triggers the expression parser. A reliable workaround involves stripping sub-second precision before serialization and adding a two-minute buffer to the to field. Seasonal call volume patterns often push interaction IDs into the next hourly bucket anyway. The padding keeps the aggregation pipeline stable. Run the query through the admin UI filter builder first to verify syntax. Logs usually just show the timestamp mismatch.

nailed the bucket alignment issue. You’ll see the same 400 error if the filter structure is wrong. The Analytics engine expects a specific shape for the interactionId parameter. It doesn’t accept a raw string value. This crashes my custom desktop builds too when the webhook data isn’t sanitized. Logs useless here.

Here is how to fix the payload structure:

  1. Wrap the ID in an array. Even if you only have one interaction, you must pass ["id"].
  2. Set the filter type to IN.
  3. Ensure the to timestamp is strictly after the from timestamp. The validator rejects zero-width ranges.

Try this JSON body for your Deno function:

{
 "dateRange": {
 "from": "2023-10-27T14:00:00.000Z",
 "to": "2023-10-27T15:00:00.000Z"
 },
 "filterType": "AND",
 "filters": [
 {
 "dimension": "interactionId",
 "type": "IN",
 "value": ["c8a9b2d1-4f5e-6789-0a1b-2c3d4e5f6789"]
 }
 ],
 "groupBy": ["interactionId"],
 "aggregations": [
 { "name": "duration", "type": "SUM" }
 ]
}

The dimension field must be exact. If you use interactionId as a key instead of inside the filter object, the parser throws that 400. Also, check your PKCE token expiration. Edge functions sometimes cache stale tokens. The request will fail silently if the scope lacks analytics:read. You might want to log the actual response body from the 400. It usually tells you exactly which field is missing.

{
 "dateRange": { "from": "2024-05-01T00:00:00.000Z", "to": "2024-05-01T23:59:59.999Z" },
 "filter": {
 "interactionId": { "type": "list", "values": ["webhook_payload_id"] }
 }
}

The array wrapper clears the initial schema check, but watch out for the QUERY TIMEZONE MISMATCH risk. The Analytics engine defaults to UTC for bucket calculations, which breaks the INTERACTION ID FILTER when paired with relative timestamps. The Admin UI Queue Analytics dashboard handles this gracefully by auto-escaping the interaction strings before submission. The raw API doesn’t offer that safety net.

Tried: Switching to fixed ISO strings anchored to US/Pacific.
Failed: The AGENT METRICS AGGREGATION still returns a 400 because the DYNAMIC FILTER PARSER rejects unescaped characters from the webhook payload.
Tried: Adding a sanitization step to strip leading slashes.
Failed: The RATE LIMIT POLICY on the analytics endpoint throttles the retry logic after three consecutive validation errors.

You’ll need to enforce strict string formatting on the interactionId before it hits the endpoint. The documentation suggests wrapping the values in a dedicated list object rather than passing raw strings. How is the current webhook implementation handling the FILTER EXPRESSION syntax before the POST request fires? The parser gets stubborn when the payload structure drifts even slightly. Might need to patch the middleware layer.

yeah so the filter structure thing is spot on - the Analytics API is really picky about how interactionId gets passed. it’s not just a string, it expects a list even if you only have one ID.

we’ve seen this same issue when pulling data from Studio flows into reporting. the webhook just dumps the ID as text, and then the query fails.

the example payload from is 90% there. the only thing is the date range - hardcoding like that means you’re stuck with that single day. you’ll want to build that dynamically.

here’s the logic:

  1. grab the interactionId from the webhook payload.
  2. build the dateRange using current time - 24 hours to current time.
  3. wrap the interactionId in an array.
  4. send it to the Analytics API.

pseudo-code:

interaction_id = webhook_payload.interactionId
start_time = now() - 24 hours
end_time = now()

payload = {
 "dateRange": {
 "from": start_time.isoformat(),
 "to": end_time.isoformat()
 },
 "filter": {
 "interactionId": {
 "type": "list",
 "values": [interaction_id]
 }
 }
}

The Admin UI timezone stuff is real - definitely keep an eye on that. the API defaults to UTC so it’ll mess things up if your webhook’s timezone is different.

hope this helps someone
