How to migrate from Telnyx to Infobip

Telnyx is a licensed telecom carrier running a CPaaS platform over its own private global IP network, with APIs for SMS, MMS, RCS, WhatsApp, voice, and email. Infobip is a global omnichannel communications platform covering those same channels plus several more. On the messaging.dev Score, Telnyx rates 78/100 and Infobip 96/100. This guide covers what you gain, what you lose, and exactly how the API request changes when you switch.

What changes when you move

Channels. Every channel Telnyx offers, Infobip also offers, so you lose no channels in the move. Both support SMS, MMS, RCS, WhatsApp, voice, and email. You gain four channels: Viber, Facebook Messenger, Telegram, and Apple Messages for Business.

Compliance and residency are a wash. Both providers are GDPR, ISO 27001, SOC 2, and HIPAA aligned, and both offer EU and US servers with a data-residency choice. Country coverage grows from 130 (Telnyx) to 190 (Infobip).

Pricing is the main tradeoff. Telnyx publishes transparent pay-as-you-go pricing billed per message part, starting around $0.004 per outbound US SMS part. Infobip is primarily quote/contract-based (contact sales), with some pay-as-you-go options and no publicly listed starting price. In exchange, Infobip adds a free trial credit (Telnyx has none) and a sandbox test environment (Telnyx has none).

SDKs and docs. Both rate “high” on documentation quality and both ship Node.js, Python, PHP, Go, and Java SDKs. Telnyx additionally lists Ruby and .NET; Infobip lists C# instead and adds SMTP alongside REST and SMPP.

How the request format differs

Telnyx quickstart:

curl -X POST https://api.telnyx.com/v2/messages \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "from": "+15551234567",
    "to": "+15559876543",
    "text": "Hello, world!"
  }'

Infobip quickstart:

curl -X POST 'https://xxxxxx.api.infobip.com/sms/2/text/advanced' \
  -H 'Authorization: App YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json' \
  -d '{"messages":[{"from":"InfoSMS","destinations":[{"to":"15551234567"}],"text":"Hello from Infobip"}]}'

Endpoint. Telnyx uses a fixed host and path, https://api.telnyx.com/v2/messages. Infobip uses an account-specific base URL, https://{base_url}.api.infobip.com/sms/2/text/advanced — you must substitute the base URL shown in your dashboard.

Authentication. Telnyx uses Authorization: Bearer YOUR_API_KEY. Infobip uses a different scheme in the same header: Authorization: App YOUR_API_KEY. Swap Bearer for App.

Payload mapping. Telnyx sends a flat object; Infobip nests everything under a messages array. The sender maps from Telnyx’s top-level from (a phone number) to Infobip’s per-message from (which can be an alphanumeric sender ID such as InfoSMS). The recipient maps from Telnyx’s top-level to to Infobip’s destinations array of { "to": ... } objects. The body field keeps the name text but moves inside each message object. Note the example numbers: Telnyx uses E.164 with a leading +; Infobip’s example omits it.

Migration checklist

1. Create an Infobip account and generate an API key from the dashboard; note your account-specific base URL.
2. Map the request fields: flat from/to/text become the nested messages → destinations structure above.
3. Swap the auth header from Bearer to App.
4. Re-point your sending code to the new host and path.
5. Register or verify your sender ID before sending live traffic.
6. Re-test using Infobip’s sandbox to validate the integration before going live.
7. Update your webhooks and delivery-report callbacks to Infobip’s format.
8. Run both providers in parallel and compare delivery results.
9. Cut over once delivery and reporting match expectations.

Watch out for

• No public pricing. Infobip’s rates are quote/contract-based with no listed starting price, whereas Telnyx published per-part pay-as-you-go rates — budget for a sales conversation.
• Ruby loses its official SDK. Telnyx ships a Ruby SDK; Infobip does not. Telnyx also lists .NET, while Infobip lists C#.
• Account-specific base URL. Unlike Telnyx’s fixed host, Infobip’s endpoint host varies per account, so hardcoding the Telnyx URL will not work.
• Sender format. Infobip’s example uses an alphanumeric sender ID rather than a phone number, which may require separate registration depending on the destination country.
