Infobip

Infobip is a global communications platform as a service (CPaaS) provider headquartered in Vodnjan, Croatia, and is Croatia's largest technology company. It sells programmable messaging, voice, video, email and customer engagement APIs on top of direct connections into mobile network operators worldwide, sitting in the aggregator layer of the telecom value chain: it buys and resells carrier connectivity, and it is the developer-facing surface that most businesses actually integrate with rather than the carriers themselves. Its API posture is openly self-serve — a free-trial account, a documentation hub at infobip.com/docs/api, first-party SDKs in six languages, a public Postman workspace, remote MCP servers, and an unauthenticated OpenAPI 3.1 endpoint at https://api.infobip.com/platform/1/openapi that returns the complete specification for all public endpoints and webhooks, plus per-product specifications for 46 products. On the network-API side Infobip is a GSMA Open Gateway participant certified for SIM Swap and Number Verification (September 2025) and an Aduna channel partner, and it publishes callable CAMARA endpoints — Number Verification, SIM Swap, Device Location Verification and KYC Match — though CAMARA access itself is sales-gated behind a contact form even while the specification is public.

Infobip publishes 6 API contracts indexed on the APIs.io network, including AI Hub API, Channels API, Connectivity API, and 3 more. Tagged areas include Telecommunications, Croatia, CPaaS, Messaging, and SMS.

The Infobip catalog on APIs.io includes 2 event-driven AsyncAPI specifications, 1 JSON-LD context, and 1 Spectral governance ruleset.

Infobip’s developer surface includes authentication, documentation, API reference, SDKs, signup flow, pricing, changelog, and 122 more developer resources.

What people ask Infobip 6

The questions people put to an LLM, and the jobs they hand an agent, that Infobip's APIs answer — each one linked to the operation that does it. Generated by API Evangelist

Infobip Channels API Send SMS messages “What's the current way to send an SMS to one person or thousands of recipients with Infobip?” Send an SMS using only query string parameters “Can I send a text message with a single GET request where everything is in the URL?” Send an SMS by URL with username and password “Can I send an SMS by passing my username and password in the query string?” Preview how an SMS text will be split and encoded “How many SMS parts will my message text be split into before I send it?”

Infobip Customer Engagement API Look up one person or list people profiles “How do I look up a customer profile in Infobip People by their email or phone?” Overwrite a person profile “Can I completely overwrite a person's profile with new data in one request?” Create a person profile “How can I add a single new customer profile to People?” Delete a person profile “Can I permanently remove a single customer's profile from People?”

Infobip Platform API List my 2FA applications “Which 2FA applications have I set up in Infobip?” Create a 2FA application “What do I need to set up a new two-factor authentication application?” Get a 2FA application's configuration “How is a specific 2FA application of mine configured?” Update a 2FA application “Can I change the settings of a 2FA application I already created?”

Infobip Connectivity API Look up phone number context with a callback report “Can Number Context lookup results be pushed to my callback server instead of returned right away?” Look up phone number context immediately “How can I find out the network and status information for a phone number in Infobip and get the answer in the same response?” Review logs of past Number Context lookups “Where can I see a history of the number lookups I've already sent?” List network activation-state reports “Which network reports on number activation state are available for my account?”

Infobip Tools API Download the full platform OpenAPI specification “Where can I download the complete OpenAPI spec covering every Infobip endpoint and webhook?” Get the OpenAPI specification for one product “How do I get just the SMS OpenAPI spec instead of the whole platform document?” List products that have their own OpenAPI spec “Which product identifiers can I use when fetching a per-product OpenAPI spec?”

Infobip AI Hub API Ask an AI assistant a question and get its answer “How do I send a user's message to my Infobip AI assistant and get a generated reply?” Retrieve relevant knowledge base chunks for a message “How can I fetch the raw knowledge base passages an assistant would match to a message, without a generated answer?”

Regulatory Posture applies to this provider. Its tags matched the Telecommunications regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it.
