// Download zuliprc-dev from your dev server
const config = {
    zuliprc: 'zuliprc-dev',
};

// Send a stream message
zulip(config).then((client) => {
    // Send a message
    const params = {
        to: 'Denmark',
        type: 'stream',
        subject: 'Castle',
        content: 'Something is rotten in the state of Denmark.'
    }

    client.messages.send(params).then(console.log);
});

// Send a private message
zulip(config).then((client) => {
    // Send a private message
    const params = {
        to: 'hamlet@example.com',
        type: 'private',
        content: 'I come not, friends, to steal away your hearts.',

# For stream messages
curl https://yourZulipDomain.zulipchat.com/api/v1/messages \
    -u BOT_EMAIL_ADDRESS:BOT_API_KEY \
    -d "type=stream" \
    -d "to=Denmark" \
    -d "subject=Castle" \
    -d "content=Something is rotten in the state of Denmark."

# For private messages
curl https://yourZulipDomain.zulipchat.com/api/v1/messages \
    -u BOT_EMAIL_ADDRESS:BOT_API_KEY \
    -d "type=private" \
    -d "to=hamlet@example.com" \
    -d "content=I come not, friends, to steal away your hearts."

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

# For private 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 "Something is rotten in the state of Denmark." \
    --user othello-bot@example.com --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5

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