Cannot get the body of email with Gmail PHP API

Question

I'm having trouble with the Gmail PHP API.

I want to retrieve the body content of emails, but I can retrieve it only for emails which have attachments! My question is why?

Here's my code so far:

// Authentication things above... $client = getClient(); $gmail = new Google_Service_Gmail($client);     $list = $gmail->users_messages->listUsersMessages('me', ['maxResults' => 1000]);  while ($list->getMessages() != null) {        foreach ($list->getMessages() as $mlist) {                        $message_id = $mlist->id;            $optParamsGet2['format'] = 'full';         $single_message = $gmail->users_messages->get('me', $message_id, $optParamsGet2);          $threadId = $single_message->getThreadId();         $payload = $single_message->getPayload();         $headers = $payload->getHeaders();         $parts = $payload->getParts();         //print_r($parts); PRINTS SOMETHING ONLY IF I HAVE ATTACHMENTS...         $body = $parts[0]['body'];         $rawData = $body->data;         $sanitizedData = strtr($rawData,'-_', '+/');         $decodedMessage = base64_decode($sanitizedData); //should display my body content     }      if ($list->getNextPageToken() != null) {         $pageToken = $list->getNextPageToken();         $list = $gmail->users_messages->listUsersMessages('me', ['pageToken' => $pageToken, 'maxResults' => 1000]);     } else {         break;     } } 

The second option to retrieve content that I know is by using the snippet located in the Headers part, but it only retrieves the 50 first characters or so, which isn't very useful.

UPDATE: You might want to check my second answer below this one for a more complete code.

Finally, I worked today, so here's the complete code answer for finding the body - thanks to @Tholle:

// Authentication things above /*  * Decode the body.  * @param : encoded body  - or null  * @return : the body if found, else FALSE;  */ function decodeBody($body) {     $rawData = $body;     $sanitizedData = strtr($rawData,'-_', '+/');     $decodedMessage = base64_decode($sanitizedData);     if(!$decodedMessage){         $decodedMessage = FALSE;     }     return $decodedMessage; }  $client = getClient(); $gmail = new Google_Service_Gmail($client);  $list = $gmail->users_messages->listUsersMessages('me', ['maxResults' => 1000]);  try{     while ($list->getMessages() != null) {          foreach ($list->getMessages() as $mlist) {              $message_id = $mlist->id;             $optParamsGet2['format'] = 'full';             $single_message = $gmail->users_messages->get('me', $message_id, $optParamsGet2);             $payload = $single_message->getPayload();              // With no attachment, the payload might be directly in the body, encoded.             $body = $payload->getBody();             $FOUND_BODY = decodeBody($body['data']);              // If we didn't find a body, let's look for the parts             if(!$FOUND_BODY) {                 $parts = $payload->getParts();                 foreach ($parts  as $part) {                     if($part['body']) {                         $FOUND_BODY = decodeBody($part['body']->data);                         break;                     }                     // Last try: if we didn't find the body in the first parts,                      // let's loop into the parts of the parts (as @Tholle suggested).                     if($part['parts'] && !$FOUND_BODY) {                         foreach ($part['parts'] as $p) {                             // replace 'text/html' by 'text/plain' if you prefer                             if($p['mimeType'] === 'text/html' && $p['body']) {                                 $FOUND_BODY = decodeBody($p['body']->data);                                 break;                             }                         }                     }                     if($FOUND_BODY) {                         break;                     }                 }             }             // Finally, print the message ID and the body             print_r($message_id . " : " . $FOUND_BODY);         }          if ($list->getNextPageToken() != null) {             $pageToken = $list->getNextPageToken();             $list = $gmail->users_messages->listUsersMessages('me', ['pageToken' => $pageToken, 'maxResults' => 1000]);         } else {             break;         }     } } catch (Exception $e) {     echo $e->getMessage(); } 

As you can see, my problem was, sometimes the body cannot be found in the payload->parts but directly in the payload->body! (plus I add the loop for multiple parts).

Hope this helps somebody else.
