How to migrate from IDM interactive digital media to Sinch

IDM interactive digital media is a German CPaaS provider that runs SMS, voice, and multichannel A2P messaging APIs from data centers in Germany. Sinch is a cloud communications platform for messaging, voice, and email that operates across multiple regions. On the messaging.dev Score the two sit far apart — IDM interactive digital media rates 47/100 and Sinch 92/100 — so this guide covers what actually changes when you re-point your sending code from one to the other.

What you gain and what you lose

Channels. You lose nothing: SMS, WhatsApp, Facebook Messenger, Telegram, and voice all exist on both platforms. Sinch adds five channels IDM interactive digital media does not offer — MMS, RCS, Viber, Apple Messages for Business, and email.

Compliance. Both carry GDPR and ISO 27001. Sinch additionally holds SOC 2 and HIPAA. No certification is lost in the move.

Data residency. IDM interactive digital media hosts exclusively in the EU (Germany) with no region choice. Sinch runs both EU and US servers, supports data-residency choice, and also lists APAC, Australia, and Brazil. You gain flexibility, but note the default API host is US-based (see below).

Pricing and credit. IDM interactive digital media prices by volume through custom enterprise quotes with no public price list. Sinch publishes pay-as-you-go pricing (approx. $0.0075 per US SMS segment) with volume and committed-use tiers, and includes free trial credit for new accounts — IDM interactive digital media offers none.

Tooling. IDM interactive digital media ships no official SDKs and no sandbox, with docs rated medium. Sinch provides SDKs for Java, Python, C#, Node.js, and PHP, a sandbox test environment, and higher-rated docs. Both expose REST and SMPP; Sinch adds SMTP for email. Both support self-onboarding.

How the request format differs

Source — IDM interactive digital media:

curl -X POST https://api.i-digital-m.com/v2/sms/send \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "to": "+4915123456789",
    "from": "IDM",
    "text": "Your order is ready to ship. Tracking: XY123456"
  }'

Target — Sinch:

curl -X POST 'https://us.sms.api.sinch.com/xms/v1/YOUR_SERVICE_PLAN_ID/batches' \
  -H 'Authorization: Bearer YOUR_API_TOKEN' \
  -H 'Content-Type: application/json' \
  -d '{"from":"+15005550006","to":["+15551234567"],"body":"Hello from Sinch"}'

Endpoint. IDM interactive digital media posts to a fixed path, .../v2/sms/send. Sinch posts to .../xms/v1/{service_plan_id}/batches — a region-specific host (us.sms.api.sinch.com) with your service_plan_id embedded in the URL path.

Authentication. Both send Authorization: Bearer <token>. IDM interactive digital media describes an OAuth2 bearer token with optional IP whitelisting; Sinch uses an API token tied to your service plan. The header shape is identical, so this is largely a credential swap.

Payload mapping. Rename the body field text → body. Keep from, but Sinch’s example uses an E.164 number rather than an alphanumeric sender like IDM. Change to from a single string to a JSON array of strings.

Migration checklist

1. Create a Sinch account (self-onboarding), then generate an API token and note your service_plan_id.
2. Map the request fields: text → body, wrap to in an array, and confirm the from sender format.
3. Re-point your sending code’s base URL to the Sinch batches endpoint, choosing the region host you want.
4. Swap the auth credential to your Sinch Bearer token.
5. Re-test against Sinch’s sandbox before sending live traffic.
6. Update delivery-receipt webhooks and callbacks to Sinch’s payload format.
7. Run both providers in parallel and compare delivery.
8. Cut over, then decommission the IDM interactive digital media integration.

Watch out for

• US-default endpoint. The quickstart host us.sms.api.sinch.com routes through US servers. If you require EU/German residency (IDM interactive digital media’s default), select an EU host and configure residency accordingly.
• Sender IDs. IDM interactive digital media accepts the alphanumeric sender IDM; Sinch’s example uses an E.164 number, and alphanumeric sender support varies by country.
• to is now an array. A single-string recipient payload will fail against Sinch.
• Fewer countries on paper. Sinch lists 150 countries covered versus IDM interactive digital media’s 180.
• Lower published SLA. Sinch’s uptime SLA is 99.95% versus IDM interactive digital media’s 99.99%.
