Why teams connect Infobip and Kustomer

Keep Kustomer and Infobip working from the same contacts, and log every call, message, and meeting back on the record, in real time and in both directions.

Kustomer holds the people the business talks to: the contacts, their phone numbers and email addresses, and which rep owns the relationship. Infobip is where the talking happens, whether that is calls, texts, email, or meetings. The two depend on the same people, and when the contact list in one drifts from the other, outreach goes to stale numbers and the record of what was said never makes it back to the account.

Stacksync syncs Customers, Conversations, Messages, Companies in Kustomer with Conversations, Numbers / Senders, Delivery Reports & Logs, Persons (People CDP) in Infobip field by field, in real time, and in both directions. Current contact details flow out to Infobip so it can reach the right person, and the calls, messages, and meetings Infobip produces flow back onto the matching record in Kustomer. You decide which system owns which fields, and conflicts resolve by rules you set.

Common use cases

  • 01 Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
  • 02 Keep customer attributes updated from billing systems so routing rules and SLAs reflect account value
  • 03 Two-way sync Persons — profiles, attributes, tags, and channel opt-in state — between the Infobip People CDP and a CRM or Postgres database so audience data stays consistent in both systems.
  • 04 Push CRM or warehouse segments into Infobip People as Persons and add them to Moments flows so triggered SMS, WhatsApp, and email campaigns fire on fresh audiences.

Common sync patterns

Where Infobip sends at scale: delivery and reply status back on the contact

Sends, bounces, opens, and replies from Infobip update fields on the contact in Kustomer, so lead status reflects what actually reached the person.

One contact list, opt-outs included

A number, address, or unsubscribe recorded in either system updates the other, so no one calls a disconnected line or messages someone who opted out.

New contacts reachable right away

A contact created or updated in Kustomer appears in Infobip within seconds, so outreach starts without exporting a list or re-keying numbers.

What you can sync between Infobip and Kustomer

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Infobip objects Kustomer objects How this pairing syncs
Conversations Omnichannel contact-center threads, agents, queues, and tags in the Conversations (CCaaS) module; read and write conversation state and messages through the Conversations API for a unified support view. Conversations Support threads across channels sync outward for analytics and CRM context. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
SMS Messages Outbound SMS sent via POST /sms/3/messages (legacy /sms/2/text/advanced); sent-message logs and delivery/seen reports read via GET /sms/1/logs and /sms/1/reports, with delivery reports and inbound (MO) messages pushed to a notifyUrl webhook. Users Agent records map conversation ownership to people in other systems. SMS Messages is specific to Infobip and Users to Kustomer — each maps to any object or custom field on the other side.
WhatsApp Messages Template, text, and media WhatsApp messages sent via POST /whatsapp/1/message/*; message status and inbound replies delivered by webhook, and approved message templates are managed under the WhatsApp sender. Teams Team assignments support routing parity and reporting. WhatsApp Messages is specific to Infobip and Teams to Kustomer — each maps to any object or custom field on the other side.
Email Transactional and bulk email sent via POST /email/3/send (multipart form); delivery, open, click, bounce, and unsubscribe events arrive by webhook, and sending domains are managed through the /email/1/domains endpoints. Tags Labels on conversations and customers sync for categorization and analytics. Email is specific to Infobip and Tags to Kustomer — each maps to any object or custom field on the other side.
Numbers / Senders Provisioned phone numbers and sender IDs used as message origins, listed and managed via the Numbers API; read to map which sender each message flows through. Notes Internal annotations carry context alongside synced conversations. Numbers / Senders is specific to Infobip and Notes to Kustomer — each maps to any object or custom field on the other side.
Delivery Reports & Logs Per-message delivery status, seen/read receipts, and error codes; pulled from GET /sms/1/reports and /sms/1/logs within a short retention window, or pushed in real time to a configured notifyUrl webhook. Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. Delivery Reports & Logs is specific to Infobip and Customers to Kustomer — each maps to any object or custom field on the other side.

How changes propagate between Infobip and Kustomer

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Infobip Kustomer Sub-second propagation

DetectionInfobip notifies Stacksync of record changes through webhook events. Delivery reports, seen/read receipts, and inbound (mobile-originated) messages are pushed in real time to a configured notifyUrl webhook per channel.

DeliveryEach detected change is written to Kustomer through its API, with automatic retries and rate-limit backoff.

Kustomer Infobip Sub-second propagation

DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.

DeliveryEach detected change is written to Infobip through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Infobip: Message-sending throughput is provisioned per account and per number/sender rather than one fixed global cap; non-messaging endpoints are throttled and return HTTP 429 Too Many Requests when usage exceeds expected levels.
  • Kustomer: Subject to the platform's API rate limits.

How the Infobip and Kustomer connectors work

Infobip

Integration surface
Infobip omnichannel REST API (JSON over HTTPS) across per-channel resources (SMS, WhatsApp, Email, Voice), the People CDP, and Conversations; a unified Messages API also spans channels
Authentication
API key sent as the header 'Authorization: App <api-key>' (recommended), with HTTP Basic authentication and OAuth 2.0 also supported; keys are limited by per-endpoint scopes, and every request must target the account's personalized base URL
Change detection
Delivery reports, seen/read receipts, and inbound (mobile-originated) messages are pushed in real time to a configured notifyUrl webhook per channel; message logs/reports (GET /sms/1/logs, /sms/1/reports) and People list endpoints are polled as a fallback
