twilio error 20404: The requested resource was not found on message fetch

TL;DR

Twilio 20404 means the message SID does not exist (or belongs to a different account): check the SID and the account it is fetched with.

Error

Twilio error 20404: The requested resource was not found

Steps

1. Verify the message SID is complete and correct Expected: no truncation or typo.
2. Fetch it with the same account that sent it Expected: account matches.
3. Check whether the message was deleted Expected: you know if it is gone for good.
4. Fix the SID source if automation mangles it Expected: future fetches work.

When to use

• Twilio 20404 on message fetch
• The SID is wrong or cross-account

When not to use

• The message exists (then check the account)
• Recently sent (then allow for propagation delay)

Tool compatibility

Variant phrasings

twilio 20404

The message was not found. Check the SID and the account.

requested resource not found twilio

Same: wrong SID, wrong account, or deleted message.

Why it happens

SIDs get truncated in logs and UIs, and subaccounts split resources. Agents fetch with whatever account is configured.

Edge cases

• Message resources are immutable; a 20404 never becomes a 200 later
• Store the full SID at send time
