Usage examples

{generate_code_example(javascript)|/messages:post|example}

{tab|curl}

{!curl-auth-credentials.md!}

# For channel messages
curl -X POST {{ api_url }}/v1/messages \
    -u EMAIL_ADDRESS:API_KEY \
    --data-urlencode type=stream \
    --data-urlencode 'to="Denmark"' \
    --data-urlencode topic=Castle \
    --data-urlencode 'content=I come not, friends, to steal away your hearts.'

# For direct messages
curl -X POST {{ api_url }}/v1/messages \
    -u EMAIL_ADDRESS:API_KEY \
    --data-urlencode type=direct \
    --data-urlencode 'to=[9]' \
    --data-urlencode 'content=With mirth and laughter let old wrinkles come.'

{tab|zulip-send}

You can use zulip-send (available after you pip install zulip) to easily send Zulips from the command-line, providing the message content via STDIN.

# For channel messages
zulip-send --stream Denmark --subject Castle \
    --user othello-bot@example.com --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5

# For direct messages
zulip-send hamlet@example.com \
    --user othello-bot@example.com --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5

Passing in the message on the command-line

If you'd like, you can also provide the message on the command-line with the -m or --message flag, as follows:

zulip-send --stream Denmark --subject Castle \
    --message 'I come not, friends, to steal away your hearts.' \
    --user othello-bot@example.com --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5

You can omit the user and api-key parameters if you have a ~/.zuliprc file.
