+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# Partner Ads Experience (PAX) API
+
+This Repository contains all of the interfaces needed to integrate with
+Google Partner Ads experience.
+
+This SDK is required when you develop your app with Typescript. For javascript
+developer, this SDK is not required as part of your app library. But it is also
+useful to check the type declaration files during integration developing
+process.
+

+
+## Quick start
+
+**Note:** The following code assumes that you develop with Javascript.
+
+Make a local copy of the repo
+
+```
+git clone https://partner-code.googlesource.com/embedded-ads/partner-ads-experience
+```
+
+### Config setup
+```js
+let paxConfig = {
+  authAccess: {
+    oauthTokenAccess: {
+      token: ${token},
+    }
+  },
+  locale: ${locale},
+  clientConfig: {
+    contentContainer: ${ads_container_element_id},
+  },
+};
+```
+To add debugging config, set:
+```js
+let paxConfig = {
+  authAccess: {
+    oauthTokenAccess: {
+      token: ${token},
+    }
+  },
+  locale: ${locale},
+  clientConfig: {
+    contentContainer: ${ads_container_element_id},
+  },
+  debuggingConfig: {
+    env: 'QA_PROD'
+  },
+};
+```
+
+### Ads required services setup
+Ads required services play the key role to communicate between the Ads app and
+the partner app during the Ads app running time.
+
+#### OAuth data
+
+```js
+let authInfoService = {
+  get: ${get_access_info_impl},
+  fix: ${fix_access_info_impl},
+};
+```
+
+#### Conversion tracking
+
+```js
+let conversionTrackingService = {
+  getSupportedConversionLabels: ${get_supported_conversion_labels_impl},
+};
+```
+
+#### Business info
+
+```js
+let businessService = {
+  getBusinessInfo: ${get_business_info_impl},
+  fixBusinessInfo: ${fix_business_info_impl},
+};
+```
+
+#### Terms and conditions
+
+```js
+let termsAndConditionsService = {
+  notify: ${notify_impl},
+};
+```
+
+### Wrap all Ads app required services
+
+```js
+let paxServices = {
+  authenticationService: authInfoService,
+  businessService: businessService,
+  conversionTrackingService: conversionTrackingService,
+  termsAndConditionsService: termsAndConditionsService,
+};
+```
+
+### Launch with the integrator
+
+```js
+// Insert the script with integrator js file from Google gstatic.com.
+let sc = document.createElement('script');
+sc.src = 'https://www.gstatic.com/pax/jimdo/dev/pax_integrator.js';
+document.body.append(sc);
+
+// Create an element to launch the Ads app.
+let rootContainer = document.getElementById(${root_element_id});
+let adsContainer = document.createElement('div');
+adsContainer.id = ${ads_container_element_id};
+rootContainer.appendChild(adsContainer);
+
+// Call launch api
+google.ads.integration.integrator.launchGoogleAds(paxConfig, paxServices);
+```
+
+### Get services supported by the Ads app
+
+```js
+const adsAppHandler = await google.ads.integration.integrator.launchGoogleAds(paxConfig, paxServices);
+const adsSupportedServices = adsAppHandler.getServices();
+```
+
+#### Get conversion tracking id from the Ads app
+
+```js
+const ctService = adsSupportedServices.conversionTrackingService;
+const conversionTrackingId = (await ctService.getConversionTrackingId(${get_conversion_tracking_id_request})).conversionTrackingId;
+```
