Details#

This integration uses pre-built, source-available 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.

Data.Police.UK Overview#

The Data.Police.UK API provides access to a wide array of UK crime data, allowing users to query information about street-level crimes, outcomes, and the location of police stations. You can leverage this data within Pipedream to build automated workflows that react to new data, analyze crime trends, or integrate with other services to enhance public awareness and safety. With Pipedream, you can create serverless workflows that connect Data.Police.UK API with other apps to streamline tasks, generate reports, or trigger alerts based on crime data.

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.

Label	Prop	Type	Description
Data.Police.UK	`dataPoliceUK`	`app`	This component uses the Data.Police.UK app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Polling interval	`timer`	`$.interface.timer`	Pipedream will poll the Data Police UK on this schedule
Date	`date`	`string`	(YYYY-MM) Limit results to a specific month. The latest month will be shown by default
Latitude	`lat`	`string`	Latitude of the requested crime area. You must use either lat/lng or poly, never both.
Longitude	`lng`	`string`	Longitude of the requested crime area. You must use either lat/lng or poly, never both.
Poly	`poly`	`string`	The lat/lng pairs which define the boundary of the custom area. The `poly` parameter is formatted in lat/lng pairs, separated by colons: `[lat],[lng]:[lat],[lng]:[lat],[lng]`. You must use either lat/lng or poly, never both.

Trigger Authentication#

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

The Data.Police.UK API does not enforce authentication.

Pipedream Overview#

Pipedream is an API that allows you to build applications that can connect to
various data sources and processes them in real-time. You can use Pipedream to
create applications that can perform ETL (Extract, Transform, and Load) tasks,
as well as to create data-driven workflows.

Some examples of applications you can build using the Pipedream API include:

An application that can extract data from a database, transform it, and then
load it into another database.
An application that can monitor a data source for changes, and then trigger a
workflow in response to those changes.
An application that can poll an API for new data, and then process that data
in real-time.
