Add the dependency in your build.gradle file:

dependencies { implementation 'com.pipedream:pipedream' }

Add the dependency in your pom.xml file:

<dependency> <groupId>com.pipedream</groupId> <artifactId>pipedream</artifactId> <version>1.1.2</version> </dependency>

Instantiate and use the client with the following:

package com.example.usage; import com.pipedream.api.BaseClient; import com.pipedream.api.resources.actions.requests.RunActionOpts; public class Example { public static void main(String[] args) { BaseClient client = BaseClient .builder() .clientId("<clientId>") .clientSecret("<clientSecret>") .projectId("YOUR_PROJECT_ID") .build(); client.actions().run( RunActionOpts .builder() .id("id") .externalUserId("external_user_id") .build() ); } }

This SDK supports two authentication methods:

If you already have a valid access token, you can use it directly:

BaseClient client = BaseClient.withToken("your-access-token") .url("https://api.example.com") .build();

The SDK can automatically handle token acquisition and refresh:

BaseClient client = BaseClient.withCredentials("client-id", "client-secret") .url("https://api.example.com") .build();

This SDK allows you to configure different environments for API requests.

import com.pipedream.api.BaseClient; import com.pipedream.api.core.Environment; BaseClient client = BaseClient .builder() .environment(Environment.Prod) .build();

You can set a custom base URL when constructing the client.

import com.pipedream.api.BaseClient; BaseClient client = BaseClient .builder() .url("https://example.com") .build();

When the API returns a non-success status code (4xx or 5xx response), an API exception will be thrown.

import com.pipedream.api.core.PipedreamApiApiException; try{ client.actions().run(...); } catch (PipedreamApiApiException e){ // Do something with the API exception... }

This SDK is built to work with any instance of OkHttpClient. By default, if no client is provided, the SDK will construct one. However, you can pass your own client like so:

import com.pipedream.api.BaseClient; import okhttp3.OkHttpClient; OkHttpClient customClient = ...; BaseClient client = BaseClient .builder() .httpClient(customClient) .build();

The SDK is instrumented with automatic retries with exponential backoff. A request will be retried as long as the request is deemed retryable and the number of retry attempts has not grown larger than the configured retry limit (default: 2). Before defaulting to exponential backoff, the SDK will first attempt to respect the Retry-After header (as either in seconds or as an HTTP date), and then the X-RateLimit-Reset header (as a Unix timestamp in epoch seconds); failing both of those, it will fall back to exponential backoff.

A request is deemed retryable when any of the following HTTP status codes is returned:

• 408 (Timeout)
• 429 (Too Many Requests)
• 5XX (Internal Server Errors)

Use the maxRetries client option to configure this behavior.

import com.pipedream.api.BaseClient; BaseClient client = BaseClient .builder() .maxRetries(1) .build();

The SDK defaults to a 60 second timeout. You can configure this with a timeout option at the client or request level.

import com.pipedream.api.BaseClient; import com.pipedream.api.core.RequestOptions; // Client level BaseClient client = BaseClient .builder() .timeout(10) .build(); // Request level client.actions().run( ..., RequestOptions .builder() .timeout(10) .build() );

The SDK allows you to add custom headers to requests. You can configure headers at the client level or at the request level.

import com.pipedream.api.BaseClient; import com.pipedream.api.core.RequestOptions; // Client level BaseClient client = BaseClient .builder() .addHeader("X-Custom-Header", "custom-value") .addHeader("X-Request-Id", "abc-123") .build(); ; // Request level client.actions().run( ..., RequestOptions .builder() .addHeader("X-Request-Header", "request-value") .build() );

The SDK provides access to raw response data, including headers, through the withRawResponse() method. The withRawResponse() method returns a raw client that wraps all responses with body() and headers() methods. (A normal client's response is identical to a raw client's response.body().)

RunHttpResponse response = client.actions().withRawResponse().run(...); System.out.println(response.body()); System.out.println(response.headers().get("X-My-Header"));

While we value open-source contributions to this SDK, this library is generated programmatically. Additions made directly to this library would have to be moved over to our generation code, otherwise they would be overwritten upon the next generated release. Feel free to open a PR as a proof of concept, but know that we will not be able to merge it as-is. We suggest opening an issue first to discuss with us!

On the other hand, contributions to the README are always very welcome!
