## StartWorkflow

`client.automations.startExecution(AutomationStartExecutionParamsbody, RequestOptionsoptions?): AutomationStartExecutionResponse`

**post** `/gitpod.v1.WorkflowService/StartWorkflow`

Starts a workflow execution.

Use this method to:

- Start workflow execution on demand
- Test workflow configurations
- Run workflows outside of automatic triggers

### Examples

- Start workflow:

  Starts a workflow execution manually.

        A Timestamp represents a point in time independent of any time zone or local
        calendar, encoded as a count of seconds and fractions of seconds at
        nanosecond resolution. The count is relative to an epoch at UTC midnight on
        January 1, 1970, in the proleptic Gregorian calendar which extends the
        Gregorian calendar backwards to year one.

        All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
        second table is needed for interpretation, using a [24-hour linear
        smear](https://developers.google.com/time/smear).

        The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
        restricting to that range, we ensure that we can convert to and from [RFC
        3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.

        # Examples

        Example 1: Compute Timestamp from POSIX `time()`.

        Timestamp timestamp;
        timestamp.set_seconds(time(NULL));
        timestamp.set_nanos(0);

        Example 2: Compute Timestamp from POSIX `gettimeofday()`.

        struct timeval tv;
        gettimeofday(&tv, NULL);

        Timestamp timestamp;
        timestamp.set_seconds(tv.tv_sec);
        timestamp.set_nanos(tv.tv_usec * 1000);

        Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.

        FILETIME ft;
        GetSystemTimeAsFileTime(&ft);
        UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;

        // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
        // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
        Timestamp timestamp;
        timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
        timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));

        Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.

        long millis = System.currentTimeMillis();

        Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
        .setNanos((int) ((millis % 1000) * 1000000)).build();

        Example 5: Compute Timestamp from Java `Instant.now()`.

        Instant now = Instant.now();

        Timestamp timestamp =
        Timestamp.newBuilder().setSeconds(now.getEpochSecond())
        .setNanos(now.getNano()).build();

        Example 6: Compute Timestamp from current time in Python.

        timestamp = Timestamp()
        timestamp.GetCurrentTime()

        # JSON Mapping

        In JSON format, the Timestamp type is encoded as a string in the
        [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
        format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
        where {year} is always expressed using four digits while {month}, {day},
        {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
        seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
        are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
        is required. A proto3 JSON serializer should always use UTC (as indicated by
        "Z") when printing the Timestamp type and a proto3 JSON parser should be
        able to accept both UTC and other timezones (as indicated by an offset).

        For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
        01:30 UTC on January 15, 2017.

        In JavaScript, one can convert a Date object to this format using the
        standard
        [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
        method. In Python, a standard `datetime.datetime` object can be converted
        to this format using
        [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
        the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
        the Joda Time's [`ISODateTimeFormat.dateTime()`](http://joda-time.sourceforge.net/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime\(\)) to obtain a formatter capable of generating timestamps in this format.

            timestamp.set_seconds(tv.tv_sec);
            timestamp.set_nanos(tv.tv_usec * 1000);

            Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.

            FILETIME ft;
            GetSystemTimeAsFileTime(&ft);
            UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;

            // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
            // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
            Timestamp timestamp;
            timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
            timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));

            Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.

            long millis = System.currentTimeMillis();

            Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
            .setNanos((int) ((millis % 1000) * 1000000)).build();

            Example 5: Compute Timestamp from Java `Instant.now()`.

            Instant now = Instant.now();

            Timestamp timestamp =
            Timestamp.newBuilder().setSeconds(now.getEpochSecond())
            .setNanos(now.getNano()).build();

            Example 6: Compute Timestamp from current time in Python.

            timestamp = Timestamp()
            timestamp.GetCurrentTime()

            # JSON Mapping

            In JSON format, the Timestamp type is encoded as a string in the
            [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
            format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
            where {year} is always expressed using four digits while {month}, {day},
            {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
            seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
            are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
            is required. A proto3 JSON serializer should always use UTC (as indicated by
            "Z") when printing the Timestamp type and a proto3 JSON parser should be
            able to accept both UTC and other timezones (as indicated by an offset).

            For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
            01:30 UTC on January 15, 2017.

            In JavaScript, one can convert a Date object to this format using the
            standard
            [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
            method. In Python, a standard `datetime.datetime` object can be converted
            to this format using
            [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
            the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
            the Joda Time's [`ISODateTimeFormat.dateTime()`](http://joda-time.sourceforge.net/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime\(\)) to obtain a formatter capable of generating timestamps in this format.
