Details

This integration uses pre-built, open source components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

Trigger Configuration

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.
LabelPropTypeDescription
Google Cloudgoogle_cloudappThis component uses the Google Cloud app.
N/Ahttp$.interface.httpThis component uses $.interface.http to generate a unique URL when the component is first instantiated. Each request to the URL will trigger the run() method of the component.
N/Adb$.service.dbThis component uses $.service.db to maintain state between component invocations.
Pub/Sub Topic Nametopicstring

Pipedream will create a Pub/Sub topic with this name in your account,
converting it to a valid Pub/Sub topic name.

Trigger Authentication

Google Cloud uses API keys for authentication. When you connect your Google Cloud account, Pipedream securely stores the keys so you can easily authenticate to Google Cloud APIs in both code and no-code steps.

When you create a service account in GCP, you'll be asked to generate a service account key. Create that key and download the key details in JSON format.

Open the key JSON in a text editor, then copy and paste its contents here.

Search Termqstring

Search for keywords star wars, screen names @starwars, or hashtags #starwars. You can also use Twitter's standard search operators.

Result Typeresult_typestringSelect a value from the drop down menu:{ "label": "Recent", "value": "recent" }{ "label": "Popular", "value": "popular" }{ "label": "Mixed", "value": "mixed" }
RetweetsincludeRetweetsstringSelect a value from the drop down menu:{ "label": "Include", "value": "include" }{ "label": "Exclude", "value": "exclude" }{ "label": "Only include retweets", "value": "only" }

LanguagelangstringSelect a value from the drop down menu.
Localelocalestring

Specify the language of the query you are sending (only ja is currently effective). This is intended for language-specific consumers and the default should work in the majority of cases.

Geocodegeocodestring

Returns tweets by users located within a given radius of the given latitude/longitude. The location is preferentially taking from the Geotagging API, but will fall back to their Twitter profile. The parameter value is specified by latitude,longitude,radius, where radius units must be specified as either mi (miles) or km (kilometers). Note that you cannot use the near operator via the API to geocode arbitrary locations; however you can use this geocode parameter to search near geocodes directly.

Since IDsince_idstring

Returns results with an ID greater than (that is, more recent than) the specified ID. There are limits to the number of Tweets which can be accessed through the API. If the limit of Tweets has occured since the since_id, the since_id will be forced to the oldest ID available.

Enrich TweetsenrichTweetsboolean

Enrich each tweet with epoch (milliseconds) and ISO8601 conversions of Twitter's created_at timestamp.

Count (advanced)countinteger

The maximum number of tweets to return per API request (up to 100)

Max API Requests per Execution (advanced)maxRequestsinteger

The maximum number of API requests to make per execution (e.g., multiple requests are required to retrieve paginated results). Note: Twitter rate limits API requests per 15 minute interval.

Action Authentication

Twitter uses OAuth authentication. When you connect your Twitter account, Pipedream will open a popup window where you can sign into Twitter and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Twitter API.

Pipedream requests the following authorization scopes when you connect your account:
