深度链接 API

概述

Branch's Deep Linking API is a powerful tool for all things Branch Links. You can programmatically generate links at scale to support all of your campaigns while tagging the links appropriately based on channel and other analytics tags.

API Limitations

细节

频率限制

  • 500/second
  • 30,000/minute

Prerequisites & API Access

In order to access the Deep Linking API, you need to have completed the following:

  1. Created a Branch Dashboard

认证

Calls to the Deep Linking API require both your Branch Key and (sometimes) Branch Secret parameter to be passed with each request. This can be obtained through the Branch Dashboard Account Settings.

Learn more about your Branch Account Profile here.

For some calls, you will also need your Branch Access Token. This can be obtained from your Branch Dashboard User Settings.

Learn more on retrieving your Access Token here.

API Usage

Create a Deep Link URL

Endpoint

POST /v1/url
Content-Type: application/json
Body: JSON parameters
Host: api2.branch.io

Request Headers

标头值必要项
Content-Typeapplication/json是

Request Body Parameters:

参数

描述

必要项

branch_key

The Branch key of the originating app; from your Branch Settings Dashboard

是

数据

The dictionary to embed with the link. Accessed as session or install parameters from the SDK. Use the data dictionary for all link control parameters that you'll find here.

否

alias

Instead of our standard encoded short url, you can specify the vanity alias. For example, instead of a random string of characters/integers, you can set the vanity alias as .app.link/devonaustin. Aliases are enforced to be unique and immutable per domain, and per link - they cannot be reused unless deleted.

最多128个字符

NOTE: If you POST to the this endpoint with the same alias, and a matching set of other POST parameters to an existing aliased link, the original will be returned to you. If it clashes and you don't specify a match, will return a HTTP 409 error.

否

type

Set to 0 by default, which represents standard Branch links created via the Branch SDK.

否
持续时间In seconds. Only set this key if you want to override the match duration for deep link matching. This is the time that Branch allows a click to remain outstanding and be eligible to be matched with a new app session. This is default set to 7200 (2 hours).否
Branch 分析参数请确保使用分析标签的组织结构标签链接，以使数据在操作后台 (Dashboard)中显示一致且易读。否
身份The identity used to identify the user. If the link is not tied to an identity, there's no need to specify an identity.Max 127 characters否

Update Existing Deep Link

🚧

链接更新提示

  • A link's data object is overwritten entirely by the Link Update API, so make sure to include all of the link's data when updating it (not just the data you're changing).
  • To update links in bulk, combine the Link Update and Link Read APIs when creating a script.
  • If you want to add custom key/value pairs to the data object, you will need to do it outside of the API Reference.

链接更新提示

  • 链接的数据对象会完全被链接更新 API 覆盖，因此请确保在更新链接时包括所有链接数据（而不仅仅是您要更改的数据）
  • To update links in bulk, combine the Link update and Link read APIs when creating a script.

The sample Python script below reads a 2-column CSV file, and updates a key specified in the script for all links listed in column A, with the values in column B:

import requests
import csv
import sys
import urllib
import json

def BranchUpdateModule(KeyV, SecretV, UpdateV, File):
    #Insert API key & App Secret from the Branch dashboard, and the Link data key you want to change in each link **
    branch_key = KeyV
    branch_secret = SecretV
    key_to_update = UpdateV


    #Insert filename for CSV containing links to update in first column, and values to add in second column **
    ifile = open(File, "r", encoding="utf-8")

    #Constants
    branchendpoint = "https://api2.branch.io/v1/url?url="
    reader = csv.reader(ifile, delimiter=',')


    # Uncomment the next line if you want the script to skip the first line of the CSV
    next(reader)

    # Loop through CSV
    for row in reader:

        # Retrieve link data for link being updated
        url = urllib.parse.quote_plus(row[0])
        getrequest = branchendpoint + url + "&branch_key=" + branch_key
        linkdata = requests.get(getrequest)
        jsonData = json.loads(linkdata.text)

        if linkdata.status_code != 200:
            print('Failed: {}'.format( getrequest))
            continue

        # Set credentials for update API
        jsonData["branch_key"] = branch_key
        jsonData["branch_secret"] = branch_secret

        #TODO for editing new value
        newValue = row[1]
        if key_to_update in jsonData:
            jsonData[key_to_update] = newValue
        if key_to_update in jsonData["data"]:
            jsonData["data"][key_to_update] = newValue

        if jsonData.get('type', None) is not None:
            del jsonData['type']
        if jsonData.get('alias', None):
            del jsonData['alias']
        payload = json.dumps(jsonData)
        #print("\n \n payload")
        #print(payload)
        putrequest = branchendpoint + url

        print(putrequest)
        r = requests.put(putrequest, json=jsonData)
        #print("\n \n")
        print(r.url)
        print(r)

        # print

    ifile.close()

Link Update Restrictions

尝试更新链接时存在一些限制：

  • Not all links are updateable, namely links with the structure of bnc.lt/c/ or bnc.lt/d/
  • The alias of a link cannot be updated, e.g. 'https://bnc.lt/test' -> 'https://bnc.lt/test1'
  • 与 Branch Link 关联的身份无法更新
  • The type of a link cannot be changed, e.g. a marketing link is type 2, and a standard link generated by our Branch SDK is type 0
  • 以下额外字段无法更新：
    • app_id
    • randomized_bundle_token
    • domain
    • state
    • creation_source
    • app_short_identifier
