Why teams connect Apollo.io and Infobip

Keep Apollo.io 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.

Apollo.io 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 People (database records), Sequences, Deals (Opportunities), Tasks and calls in Apollo.io 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 Apollo.io. You decide which system owns which fields, and conflicts resolve by rules you set.

Common use cases

  • 01 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • 02 Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
  • 03 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.
  • 04 Trigger transactional SMS, WhatsApp, and email sends from database or application events (order shipped, OTP, appointment reminder) through the channel send endpoints.

Common sync patterns

Calls, messages, and meetings on the record

Activity handled in Infobip appears on the matching contact and account in Apollo.io, so the next person sees the full history without leaving the CRM.

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 Apollo.io, 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.

What you can sync between Apollo.io and Infobip

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.

Apollo.io objects Infobip objects How this pairing syncs
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Persons (People CDP) Contact profiles in the People module holding attributes, tags, and multi-channel contact data (mobile, email); full CRUD via GET/POST/PUT/DELETE /people/2/persons, so Infobip is both a source and a destination for contact records. Accounts is specific to Apollo.io and Persons (People CDP) to Infobip — each maps to any object or custom field on the other side.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. 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. People (database records) is specific to Apollo.io and SMS Messages to Infobip — each maps to any object or custom field on the other side.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. 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. Sequences is specific to Apollo.io and WhatsApp Messages to Infobip — each maps to any object or custom field on the other side.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. 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. Deals (Opportunities) is specific to Apollo.io and Email to Infobip — each maps to any object or custom field on the other side.
Tasks and calls Rep activity records synced for activity reporting and coaching workflows. 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. Tasks and calls is specific to Apollo.io and Conversations to Infobip — each maps to any object or custom field on the other side.
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. 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. Custom fields is specific to Apollo.io and Numbers / Senders to Infobip — each maps to any object or custom field on the other side.

How changes propagate between Apollo.io and Infobip

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.

Apollo.io Infobip Interval-based propagation

DetectionStacksync polls Apollo.io for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at timestamps.

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

Infobip Apollo.io 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 Apollo.io through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Apollo.io: Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls.
  • 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.

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
