How to migrate from SendPulse to Infobip

SendPulse is a multi-channel marketing and messaging platform built around email, SMS, and chat channels (WhatsApp, Telegram, Viber, Facebook Messenger) exposed through a unified REST API. Infobip is a global omnichannel communications platform covering SMS, RCS, voice, email, and more. On the messaging.dev Score, SendPulse rates 63/100 and Infobip 96/100 — this guide covers what actually changes when you re-point your sending code from one to the other.

What changes when you move

Channels you gain. Both platforms support SMS, WhatsApp, Viber, Facebook Messenger, Telegram, and email, so nothing in your current SendPulse setup disappears. Infobip adds MMS, RCS, Apple Messages for Business, and voice — four channels SendPulse does not offer.

Compliance. Both are GDPR-aligned. Infobip additionally carries ISO 27001, SOC 2, and HIPAA certifications that SendPulse does not list — relevant if you handle regulated data.

Data residency. Both run EU and US servers. Infobip also lets you choose your residency region and operates in APAC, Latin America, the Middle East, and Africa; SendPulse offers no region choice.

Pricing. This is the biggest trade-off. SendPulse is pay-as-you-go with publicly listed per-message SMS pricing (from €0.01) plus a free-forever plan. Infobip is primarily quote/contract-based (contact sales), with some pay-as-you-go options and no publicly listed SMS price — expect a rate quote rather than a published rate card. Both offer free developer credit to start.

SDKs, sandbox, docs. Both document their APIs well and both ship PHP, Python, Java, Node.js, and C# SDKs. Infobip adds Go but drops Ruby, so a SendPulse Ruby integration has no official Infobip equivalent. Infobip also provides a sandbox test environment; SendPulse has none.

How the request format differs

SendPulse quickstart:

curl -X POST https://api.sendpulse.com/sms/send \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "sender": "SenderName",
    "phones": ["380931258293"],
    "body": "Hello from SendPulse"
  }'

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"}]}'

Three things change:

• Endpoint. SendPulse posts to a fixed host, https://api.sendpulse.com/sms/send. Infobip uses an account-specific base URL — https://{base_url}.api.infobip.com/sms/2/text/advanced — so read your personal subdomain from the dashboard.
• Authentication. SendPulse uses OAuth2 client_credentials: you POST client_id/client_secret to get a one-hour Bearer token (or use a static key) and send Authorization: Bearer <token>. Infobip uses a static API key sent as Authorization: App {api_key}, letting you drop the token-exchange step entirely.
• Payload. SendPulse sends a flat object; Infobip wraps everything in a messages array. The recipient moves from phones: ["..."] to destinations: [{"to": "..."}], the sender field renames from sender to from, and the body renames from body to text.

Migration checklist

1. Create an Infobip account and generate an API key in the dashboard.
2. Note your account-specific base URL subdomain.
3. Map the request fields: sender→from, phones→destinations[].to, body→text, all wrapped in a messages array.
4. Swap the auth: replace the OAuth2 token exchange with the static Authorization: App {api_key} header.
5. Re-point your sending code to the new endpoint, or adopt an official SDK.
6. Re-test against Infobip’s sandbox before sending any live traffic.
7. Update your delivery-report and webhook callbacks to Infobip’s format.
8. Run both providers in parallel, then cut over once delivery and callbacks look correct.

Watch out for

• Pricing transparency. You lose SendPulse’s published per-SMS rates; Infobip pricing is mostly quote-based, so budget for a sales conversation.
• No Ruby SDK. Infobip ships Go instead of Ruby — port any Ruby integration to REST or another language.
• Otherwise net-positive. In this direction you lose no channels and no certifications; the migration cost is code changes, not lost capability.
