Migrate to Bird without downtime.
Four playbooks. Each one maps the source API to Bird's, shows the same flow in both SDKs, lays out a dual-write plan for the cutover, and is honest about the corners where Bird doesn't have an equivalent yet. No magic. No 30-day rip-and-replace.
Four playbooks. Pick your source.
Migrate from Twilio.
Concept mapping for Messages, Verify, Lookup, Voice, and Notify. Side-by-side OTP code diff. Webhook signature differences (SHA-1 + URL signing vs HMAC-SHA256 + timestamp). Dual-write strategy and 8-step cutover checklist. Honest about Conversations, Studio, Frontline, and TaskRouter — no Bird equivalent today.
Read the playbook→Migrate from SendGrid.
DKIM/SPF/DMARC dual-write plan with TTL lowering. 14-day IP-reputation warm-up across both vendors. Suppression-list import via bird.suppressions.import. Event mapping for delivered, bounce, open, click, unsubscribe. sgMail.send to bird.emails.send code diff.
Read the playbook→Migrate from MessageBird (classic) to Bird.
Namespace shift from messagebird.* to bird.*, base URL from rest.messagebird.com to api.bird.com/v1. Deprecated-endpoint table with v1 replacements. Dual-key window through Dec 31 2026 — classic keys keep working. Idempotency keys now required on all POSTs.
Read the playbook→Migrate from Prelude.
Verify-specific playbook: concept mapping for verification.create, side-by-side code diff, fraud-signal comparison (risk_score plus reason codes), 7-day dual-write window, cutover checklist. Honest sub-section on when not to migrate — if verify is your whole need, Prelude is sharp.
Read the playbook→Same shape every time. Every playbook has six sections.
A concept-mapping table from the source API to Bird's, a side-by-side code diff of the most important flow, the webhook-signature differences, a dual-write strategy with parallel dispatch and per-route delivery comparison, an 8-step cutover checklist, and an honest list of what doesn't have a Bird equivalent today. We don't hide the gaps.

Production migrations get a shared Slack channel and a named engineer for the dual-write window. Email migrations@bird.com with your monthly volume and we'll line it up.
